Really fun, the music and art style really vibed with me plus it was juicy to play. I'd suggest adding an auto-reload for when the player uses all of their bullets to make the game flow a bit better. I look forward to more!
Yeah one of my biggest takeaways was making the pistol less exhausting to use, so in addition to auto-reload I'm thinking that the pistols will be full auto, but with a small fire-speed penalty if you're holding down the mouse rather than clicking.
