There is a tutorial for movement and shooting follow it. If you need to reset hit the stop scripts symbol and press the R key. If you want to add a section of the game comment below with a link. THERE IS STILL SOME BUGS I'M WORKING ON IT
Thanks for the help Scratch Wiki for the projectiles tutorial and thanks to Greatguy123 (I used your sprite in Top down zombie survival scroller remix as a base and went from there.) And thanks to every forum page for the help on every problem I don't remember. Thanks to camp00s for some of the sprites.
