Press green flag to start obviously. Then use the arrow keys to move. Left and right arrow key move left and right and down arrow key to dash downward. Every time the snare drum plays you will jump and when the base drum plays you will shout out a fast laser. Also, you can kill enemies using the laser and if you fall on the red ones fast enough. See what accuracy and kills you can get. PS don't Judge my trash code.
I got inspiration from Bouncy Heroes by theChAOTiC.
