press and/or hold 'space' to spawn a bullet. you can change the bullet from a normal bullet , a bone, a rocket, a spade, and a... dog? by using the 'bullet sprite' bar. don't spam the dog if the soul color is yellow or white you can shoot bullets to break the other bullets by pressing and/or holding 'z'. the white soul has a faster fire rate if the soul color is green you can't move. [i tried to make the shield but it did not work] the orange soul makes you go much faster but bullets speed up too. the blue soul adds gravity i tried to make 2 player but it did not work.
