Up arrow: move up Down arrow: move down Space: shoot
UPDATE: I made the character movement a lot smoother with help from Fishy Starter by willdbk. You can play their game here https://scratch.mit.edu/projects/71874412/ I hope to expand on this further by adding more customisation options, better animations and maybe different levels. For now I think it's in a good state to be played, so please enjoy! Ideas and suggestions are always welcome :) Tell me what you think!
