One button tiny physic-based platformer made in Pico 8 with code under 1024 compressed bytes, made for Pico1k jam 2022

You can use any button (like c, v or arrow keys) to jump, you have infinite double-jumps and have to reach the end of the randomized tunnel. The number at the top is a timer (in frames since start of the level)

this game is lit lit lit lit*****


very fun! feels like playing as an intestinal parasite, but like in a cute way lol



i won by spamming the arrow keys (great game)



the 1512 didnt matter bc igot insanely lucky with perfectly getting through 3 small corridors which were the only 3

that was satisfying af tho


this is my best score


lmao i got 1569

im not gonna count this bc the track was suspiciously short idk what happened

good luck

i think the first attempt is always the fastest but idk how tf i got this



15 frames off but this was insane, i did mess up a bit tho

my friend was watching

first sub 1900

i tried posting a screenshot but I pressed a hotkey that reset uit before i could :


i got 1907

I had one run where if I didn't make a few mistakes I could have beaten Yoon's run of 1914. In the end I got 1930.

best score i got was 1972


I know its not better than YoomKim, but I am very proud of my 1940


1968! Barely managed to beat Vospi's score, I'm the champion 😎

Really impressive that you squeezed music in too! The tunnel looks really cool - the design is distinct and clear!

Really good casual game with a simple concept, but really well done. The physics are good. The procedural bowel is interesting too... More I explore games which you made, more attractive seems to me Pico8 as games engine. Again you made a cool game. I hope that you will be with us for the next LudumDare. I wish you the best. I guess that my score is honourable - 4141 ++


Thanks! The most important thing Pico 8 do for me is limiting the scope, so I can start a very small project without being overwhelmed by pressure. This 1k jam also help with that. Also the "immediate" rendering appeal to me, you can just draw whatever you want from code directly. 

Unfortunately I will not be there for next LudumDare, I'm a bit sad but I will surely find other jams to do soon.

I understand you. Little games don't need to be created using a big complex solution like Unity or Unreal. I guess that Pico8 works with an ECS system. I like that. For the games jam, it is a really good alternative - clever and easiest. I hope that all is fine for you. I keep an eye on your projects. I wish you the best. Salut Antoine ++

Great time. Would love an android apk. My first time was 3889.


Can't help but say that music is something to improve upon most definitely (as a person teaching music production). The melodic part could be less erratic, could disappear for a period of time to be less irritating; also there's a time when its volume jumps up for some reason, which is even more puzzling considering that I would assume the music is generated, not pre-recorded?

Honestly a great game. :)

Damn, you definitely have a knack for catchy simple games; I follow you since Combo Pool which is still on my phone. :)

Seems like a good start can make or break your record, so a button check to start the game would be very nice to have, as a restart hotkey/option would be.

edit: one can accidentally press again when finishing (which can happen when your finish is up top and you're mashing to touch it quicker) and that resets a record, it was my best run by far but I didn't see it. how about have at least a "double click proof" for it?

even if not for this one, I hope I'm at least being helpful for future project in terms of user experience. the game feels great to me and invites to play and compete, I'll send it to a couple of my friends; so I'm trying to describe the things that can hinder the competitive feel to it, basic failsafes. Sorry if you're well aware and just don't treat this as a big deal :)

You are welcome to give critical feedbacks! You can use ctrl+r or "enter->reset cart" to reset the game (but it also reset the level, maybe it could have been interesting to let people have multiple tries at the same level)

For the music, yeah you are right, it was kinda a placeholder at first but I wanted to release the game, maybe I will change it latter. It will still be very coarse as the constraint limits what I can do.

For the "double click proof" at the end, it's a good idea but I didn't have the space (in the 1024 bytes allowed by the jam) to do it, I'm already glad I could show the timer at the top :D

Very cool! 2514! :)

Really cool graphics effect with the tunnel! Nice chill experience. Now I know how a tic tac feels.

I love this so much

its got that nice classic arcade style, nothing too complicated but still fun

Cool way to do the graphics and a solid little game!

Felt very... intestinal :)

Very Nice!

Ta bueno

nice game, time 3959
