I actually left out the autofire intentionally, because I didn't want to limit the potential firerate, but in retrospect, I think it could have been beneficial to have it at least as an option. Thanks for the feedback!
That could be implemented as an upgrade after like 50 points or something! Probably not in a 48h span like that gamejam but if you go back to it could clearly see a dozen of upgrades to chose from troughout the game
