list of changes: - keyboard controls (arrow keys, x and z) - tweaked health system - added flash when getting hit - added particle effects for juice this makes the game a lot more fun in my opinion. mainly the keyboard controls though really. the rest is just random tweaks and bugfixes I decided to make there is an issue where if two bullets hit two different targets on the same frame, only one target is actually destroyed. unfortunately I'm not quite sure how to fix it without reworking the entire bullet system
