[MINOR SEZURE WARNING FOR IMPOSSIBLE MODE] IMPORTANT: If the game freezes when you play, and you instantly die, reload the page (no idea why it happens :/) I suggest you don't okay in fullscreen mode it lags a lot for some reason :/ Press 1,2,3,4.....9 and 0 to switch waves in the beginning (there are 10!!), and space to start, like it says. Press/hold space or mouse to go up and down, just like in the game geometry dash! (Personally, I prefer space bar, but that could just be me.) Don't touch the top or bottom of the screen, or the obsticklez or you'll die. It can lag a bit, but if you're having lag issues you can run it on turbo warp, thanks to @Mooshroom-09 heres the link: Turbowarp.org/202395548 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ MrMeow_Meow added a low lag mode! Press L at any time to toggle it, and it'll say whether it is on or not. The low lag mode doesn't entirely work :P It just eliminates the particles, which would be the most obvious source of lag. Nobody ever reads to down here, so if you managed to, then comment, "Gertrude"
If normal mode is too hard for you put low power mode on it makes it easier. I suggest that you don't play for too long it may hurt your eyes.
