Stability Failing

A short story sets off a grand adventure of arcady, platform-hopping fun in an increasingly unstable world.

This is my submission for Ludum Dare 49, Theme: "Unstable"


Left/Right: Move character
Up/Down: Slow down or Speed up the platforms
Z/X: Jump

Note: you can press ENTER and SKIP TUTORIAL if you'd like to start the game at level 12


As the levels progress, various aspects of the game begin to breakdown...

(try to reach at least level 11 to see the full instability)


First, your permanent platforms start to crumble. Then, the walls give way while dead-pixels fill your screen. Even your character isn't immune to the madness. By level 11, the game has fully broken down and you play like this for as long as possible. There are bits of story sprinkled throughout, all the way to level 300+.

Here are some examples of later stages:


  • Platforms crumble faster as the levels wear on.
  • More and more dead pixels will fill the screen as the levels progress.
  • The storyline loosely progresses all the way past level 300! I don't expect anyone to make it this far, however it is there for the intrepid - and talented - soul.

@Notester82 nice run! Thanks for the kind words.

I've added a menu item to SKIP TUTORIAL if you'd like to start at the later levels.
