Download Pico Map Viewer


Hey folks, I made a little tool to display and save Pico-8 graphics of your *.p8 files:

You can download it


It will save the spritesheet and map separately as .png files.

I hope you enjoy it!

There are 5 ranks to climb up.
Kill the enemy ships and don't let them escape.

Thanks @dw817 for this challenge!

You can shoot Lasers or Torpedos on c/v or z(y)/x
-Lasers cost 1 energy fired on Z(Y) / C
-Torpedos cost 2 energy fired on V / X

Move the crosshairs with your arrow keys.


The aiming is pixel perfect for the white enemy parts
-The laser checks for 1 pixel and you have to aim very precisely
-The torpedos checks for 5 pixels in a "+" formation.

A little program simulating recursion graphically.


  • Y Button to call the function
  • X Button to finish ( go back ) a function call.

It is only a simulation. So it should not be possible to go back and forth but I had to stop the calls and thought it would be funny to have some control during the process.

Endless Underground Snake is online!

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. For future updates I plan to fill those rooms with new creatures and paths.

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

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.
    The button pressed/ next move to be done will show up in the lower right corner
  • By pressing X / V you can show the mini-map.
  • By pressing Y / Z / C you can dig up/down.
    Tunnel commands show up und the lower left corner

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.
