the controls are random they will be YGHJ, WASD, or arrow keys. You are the black circle. When the black circle says "Switched!!" the controls might change. Avoid the red shapes. Press space to boost (The blue bar at the top is your boost charge).
I used @MathMathMath 's cloud tutorial. Sorry to those who have AZERTY layouts. Please note that on account of scratch 3.0 the highscores are ruined.
