This game is a demake of and an homage to Hollow Knight, a game by Team Cherry.  Made for the 2018 Demake Jam.

Explore an insect underworld, find the six charms and beat all the bosses.


Arrow keys for movement, for jump, to attack. 
Striking enemies earns soul, which you can spend to heal - hold down to do so.
Benches serve as checkpoints - to sit down, press up when near a bench. You'll heal all your wounds, but enemies will respawn as well.

My one complaint is that if you try to heal with not enough soul, it uses the soul but doesn't heal you at all. Otherwise great game


are you supposed to be able to wall jump on a screen transition?


This is such a great game and so good as a demake. The animations especially blew me away. I was wondering how you did the sword swipe animations. In the sprite sheet they are multi-coloured, which makes me think you used code to set those pixels at various times to the specific white/grey in action? Do you mind explaining a bit of how you made those visuals, however you did? @Jakub Wasilewski

Sure. It's a palette-based effect. Each frame, before the swipe is drawn, a continuous band of colors is set to various shades of gray, while all others are set to transparent. Each frame, the "band" in the colors moves one step forward, giving the impression of an animated swipe.

The item "glow" animation uses the same approach for a different effect (at sprite #41).

Wow, very interesting! If I am able to figure it out and implement it, would you mind me using this method with credits to you?

Feel free! No need for credit - palette cycling is an old, old technique with a lot of history behind it. It can be used for lots of cool stuff, eg.

In any case, have fun!

Alright, I appreciate you explaining and pointing me in the right direction (:

it is to hard, the flying enemies are annoying and moving forwards when using the nail isn't intuitive at all.

This is great!  It demonstrates a genuinely a better understanding of the non-linear structure of Metroidvanias than a lot of games that claim that genre and sell well.  The map construction is great even besides that.

If this had sound it would be incredible.  As a minor aside, if you want to put audio feedback in games but don't have time to make the sounds, an indie dev created a little program that randomly writes sound effects for just that purpose.  Look up "rsfx"

I kind of wish that after the boss you could do a new game +, since I apparently missed one of the charms.


heyo im a hollow knight speedrunner and not going to lie this game was a very fun route to tackle plus the final fight was super challenging with just one nail upgrade. Heres how I did!

Super cool! 1:51 is much lower than I'd expect, love the high jump glitch (even though it means there's a bug somewhere :)).


me and a runner named Onion have pushed it down to 1:20

nice game man


Nice game!  For me, the game was hardest near the beginning when the character was weak and I was still getting used to the controls.  The mechanics felt somewhat clunky, but I kind of got used to it after a while.  The graphics and setting added zest to the experience, and I liked by how the map design l a sense of exploration even within the game's small scale.  The overall game length felt good for playing in a single sitting, which a satisfying level of challenge.  Having a gauntlet of regular enemies as the final boss battle was kind of disappointing, but I guess that's because this was made in a limited amount of time for a game jam.

I never played the original game this is based on so I don't whether it successfully captured the spirit of the original, but I think this game stands on its own as a nice bite-sized action-platformer.


went past the area where it said "claim your destiny" then it sent me to the main menu, i clicked z and now im at the start and cant move

Yeah that's the end of the game

Nice game! The visuals are very nice to me

Controls are really weird to me. Speed is too fast and it's hard to get to hitboxes

Anyways, good job

Cool demake.


it's a good game but it would be better if you put playable controls


educate yourself on pico8

idk if it's intentional, but if you slash upwards right after you jump, you go three times as far!
anyways it's a great game :D

and i may or may not have exploited it into oblivon


you dont need anything other than nail to beat the game if you use this


cool demake, the visuals are great.

The game doesn't appear to start for me

anyone know if its possible to save progress?

up at a bench

doesn't seem to work for me

did you download it?

only in original hollow knight

nah it works in this one too.

This games controls are SOOOO weird! It seems like I land a move, but it never actually lands. Plus, The fly enemies are WAY to annoying. Sometimes, there's a delay when I want to attack! The move sometimes NEVER lands. Hopefully, the controls can be updated (along with other quality-of-life improvements) in a future update. Oh, I forgot to mention that you did a good job with this game.

controls: its pico-8 wdym theyre weird.

attack delay: that bc you have a bad computer.

the move not landing: the actual white part of the slash is the attack.

flying enemies: jump then attack.

Hello. I am an aspiring game designer making a metroidvania in Pico-8. I was wondering if I could use some of your code in my game. (With credit of course)

(1 edit)

the game doesnt react to my controls pls help

I found that if on the first bench that if your hit you get pushed up

me too lol


getting all the charms and then sitting at a bench is so nice

im pressing z but it doesnt work

German/French keyboard, maybe? If so, just press whatever key is in the same space as Z in a QWERTY keyboard (or just can use C/V in place of Z/X) :)

i tried again but i do have the qwerty keyboard and it doesnt work

try c

I just got PICO-8, when I load it however it says Runtime error line 63 tab 0

It appears to be a bug on the PICO-8 end, introduced in a recent update. It affects most of my carts and I'd have to work around it by changing the carts one by one, so for now I contacted Zep (the creator of PICO-8) to see if I can get it fixed in a future version.

(EDIT: zep tells me that the bug will be fixed in the next PICO-8 version, 0.2.1.c)

This cart will work fine in any 0.2.0 or earlier version (you can get those at

I think that's the problem, since I think I have 0.2.1. Thanks for the list


I know this comment is very late, considering the game jam was in 2018, but this is a great game. The platforming to charms is pretty difficult but fun to get through, and the boss battles weren't impossibly hard.

Thanks! Difficulty is really hard to get right in jam games - you have basically no time for playtesting, and the only person testing the game (you) has so much practice that it's very easy to make things almost impossible for new players :)

I also have a question about the gameplay, sometimes if you look up and press attack and jump at the same time, the knight goes flying up to the top of the screen. I think someone mentioned this in the cart you posted on Lexaloffle as well.

Possibly a bug? This game has quite a lot of quick and dirty code ;)

Hi, I have been working on a version of this with a handful of sprite changes, I was wondering if I could post it, giving proper credit of course?

Not sure if you will see this since it's been another whole year but just in case I guess ¯\_(ツ)_/¯


Cool, but combat and movement is slippery and ruins the game. I'd advise giving the dash a separate button and removing the annoying little steps forward the knight makes when striking, it makes you hit an enemy and them go straight into them without wanting to. Also, it would be a great improvement if the movements weren't momentum based, it makes platforming a nightmare. I can't complain too much though, I'm just happy to see a hollow knight fan game.


So I just played further into this game, and I must say that the wall climb ability is a nightmare. It actually makes platforming harder. Also, sometimes I try to heal but I don't have quite enough soul, so I just drain my soul but don't get a mask. I like the art and can see that this has lots of effort put into it, but it REALLY needs work.

you do realize that this is a jam game which probably won't get updated, right?


Yes, and that was meant as constructive criticism, I'm sorry if it came off as angry. I really like this game, and I'm really happy to see a Hollow Knight demake, I couldn't find any for a while. I did not know it was a jam game. In that case, this is amazing considering it was made in a limited amount of time. Good work!

sorry for misunderstanding, but yeah, great job devs!

No worries - feedback is valuable, even for a jam game :) As you both noticed, it's unlikely I'll ever update this - but it's never a problem hearing what others think, even if it's negative. I actually agree with a lot of the issues - but I'm still really happy with the game considering the whole thing was done in 6 days ;)

Great fun! Works well in browser but when I download it, I get a black screen after leaving the first room.

That's weird - what PICO-8 version is this on, and is this for the minified .png or editable .p8 version?

This is on the latest version of pico8, and with both versions of the cartridge

Beautiful pixel art, but the gravity is too big, and controls feel slippery. This makes falling puzzles excruciating to the point of being no fun :-/

finished with 4/6 charms, not doing again!! but only because its long. great game!


Man, the gravity is faster in this game. I have to respond earlier to prevent falling in wrong spot.

Anyways, nice short metroidvania.

great job looks amazing and the controls are also amazing

I was just looking through some of your past work after admiring your progress on Slipways. I'd seen some of your other pico-8 projects but hadn't come across this. Amazing demake! I didn't see this on the BBS though. Is there a p8 cartridge somewhere, or maybe a way to convert the JS version to p8?


It's not on the BBS for some reason - could have sworn I've uploaded it there. I'll have to submit it one of these days, but I'd have to minify it so it works in the .png format etc.

For now, here is a link to the .p8 if you're curious:


your link is pretty much dead so could you put it back up

Thanks! The link is indeed dead by now. Any chance you could re-share it or upload it to the BBS? Thanks and keep up the great work:)

just completed this , totally awesome game !


i wish it wasn't so difficult i understand it is a game jam but you could have eased up on the spikes dude. great overall good job.


why is it so hard? Just seems like wasted potential. I mean, the art and style and the original idea is the best!!!!! But, It's too hard and there are too many level hazards. But other and that, It's great!

wow this is amazing

the game is also harder than the original

i really really love this game and i would just love to see some huge boss it would be the coolest thing. this is by far my favourite game on and favourite pico 8 game a boss would just be amazing.

i would love to see more added on to this game as i can only see the original and not play it because i have a chrome book please please add more on to this game i, love it


i have beat the origanel game and its my number 1 game of all time, its nice to see a 8 bit type game of it that isnt bad and is fun to play. great work on this
