Just played it on Windows instead :D Good submission! Sometimes I felt a little confused that a bun had randomly snuck up on me and drained all my HP without me realizing it was even there. I love the graphics, they're really cute and charming. I would speed up the bullets since it felt a little hard to aim them though, and also sometimes I just wasn't able to shoot even when I wasn't reloading.
With a few details worked out this could be a really nice arena shooter. Thanks for submitting!
