Nice game! Had a really cohesive art style, and I really liked how core to the game the use of the limitation was, with how many different uses the singular bullet resource had. I think my only recommendations would be to make it a little more clear that after the shop that you'll regain bullets (and maybe how many), and also how much health enemies have left (maybe something simple like fading them out as they lose health). Overall, great job on the game!
