Press space or click to jump over the blocks hurtling towards the player. If the double jump orb is lit, you can jump while inside of it to shoot yourself back at the ground. When you first load the project, it might take a few seconds to load, but it only does this the first time.
I remade the moving part renderer using pixelate effect instead of fisheye, so I could remove all 4000x4000 size backgrounds that could crash on mobile. I also made it framerate independent by separating the game logic from the rendering.
