I've made some great changes to the game, including endless gameplay with hundreds of different, procedurally generated levels, an ability to dig underground, a tutorial intro screen as well as a mini-map.

If you want to skip the intro screen hit Y/Z
I hope you enjoy!

Jan 2020 Update: implemented help arrows

Nov 2019 Update: implemented reset function


Endless Snake is a mix of skill-, memory- and puzzle-game concepts taking place in a dungeon.
The gameplay goes on infinitely and there are hundreds of different, procedurally generated levels.


You control the snake with the arrow keys.
-By pressing X / V you can sacrifice one life and reset the snake to the last door used.
-By pressing Y / Z / C you can hide/ show helping arrows which will guide you along your way.

The map is a square of 3x3 rooms
Follow the arrows in their order to reach the end


  • Kill all spiders to open the last door and collect their eggs to get extra points.
  • Plan your way as you might need to come back to a room again.
  • Spiders produce eggs over time, more eggs more bonus-points.
  • Eggs are also needed to dig underground. Let the spiders live for a while to produce more eggs.
  • The longer your snake the higher your score will be.

This is pretty nice! Happy coding \o/

Good but instead of jerking back from hitting a wall, suggest player start overe where they first entered this particular room.

As it is you can get yourself trapped just once and this will use up all your lives.

This is really tricky! Thanks for the interesting game - I think I'll have some fun learning strategies for this.

P#69819 2019-11-11 17:55

yes! you are absolutely right and I planned to add a feature where you can give up a life to jump back to the last door used :)
An other idea I had is to implement a skill with a cool down, which enables you to tunnel yourself. Unfortunately this second idea came to me quite late and is kind of difficult to implement in the design I use now. I am planning an android version with higher resolution, bigger maps, map elements like bridges, tunnels and such skills as mentioned above in the future. But it will need to wait since I am currently working on a 2d top down game with rpg elements.

yes I know if you don't know the path it is really a hard try and error strategy with good memorization needed. If you feel like it is getting to hard check out my instagram acc (yesyoorgames), I posted a walkthrough video of that lvl there ;)

Also without those skills mentioned above the order to visit the rooms is pretty much fixed for this first level. In a future version I hope that a different level design and features as tunneling will be able to fix this.

Thank you all for checking it out and your feedback! I really appreciate
it ! :)


reset function is implemented now ;)

If you plan to write a version for Android, @Yesyoor, you will have to leave Pico-8 behind. Unfortunately Pico-8 does not run on the Android nor is there a program to convert a cart to APK (native Android and cellphone executable).

The main reason I'm in PICO-8 is simplicity. Sometimes I can really get bogged down by coding in a more complex language.

Pico-8 is refreshingly simple to program in.

Yes true, but I was developing android apps before I came to pico 8. I am currently working on a 2D top down game using libgdx. I would use libgdx again to realize it on Android and all other platforms. But as you said it, pico-8 is perfect for checking out ideas and building prototypes in a very short time (and pretty environment too!)

Any wished/ ideas for future updates? :)
