This is pretty great! Surprisingly deep for such a short game jam so nicely done. Just some minor feedback but as people have mentioned a health bar would be a good addition since it's hard to tell the character's color. I would also love some indicator of the reload status too, just so I know when I can shoot again without clicking space since the bouncing bullet can make that risky. Maybe a circle around the player that fills up and goes away once you're ready to fire again?
