Arrow keys or WAD to move. Press S or Down arrow to crouch. Blue pads are bouncy. Yellow pads are speedy. Red and the void kill you. Don't let go of crouch if you're crouching under something. If you do, press R and it'll fix it. Tips: Hold the jump key for a higher jump, hold the jump key while bouncing for a higher bounce.
