Turbowarp: https://turbowarp.org/504721454 WASD/arrow keys/touch screen are controls space/click to restart when you die (other keys take you back) left/A and right/D to change difficulty settings on the menu (sorry mobile users) "It's basically like DDR, press arrow when arrow over other arrow. And uhhh don't die."
Thanks Realboxing for the real project, you're awesome!!
