Endless Arcade Platformer

You don't know who you are or where you're going. All you know is that you're very small and those yellow diamonds look enticing.  Jump and wall-jump your way through various obstacles that get faster the further you go, while avoiding threatening red-colored objects and grabbing nondescript yellow diamonds!

Left and Right arrow keys, plus A and D, move side to side. Space, Up, and W all jump, while Down and S can be used for a quick landing.

It's not a perfect application, there are bugs. But I can't say I have the motivation to fix them, so here we are.
