Very fun idea, especially once I realized that I had to watch out and make sure the gunners didn't get hurt rather than treating the bullet as the only "player character" of mine which mattered. I do second what's already been said about finding a fix for when the best way to point in the direction you want is to have your mouse outside of the game window, though.

I'm probably going to make a post-jam version of the game with the suggestions I'm getting in mind, like window locking. I didn't realize that it was an issue during development since the editor version works fine with the mouse outside the window, so I know now to keep it in mind. I also considered having the bullet pointed towards the mouse, but I ultimately decided against that since at the time it seemed it would be better if the projectiles were shot towards the mouse like in most top down shooters. I should have made it an option, I just didn't have the time or foresight to do so. Still, it's great to hear you found it fun, thank you for the feedback!
