Thanks for the feedback! I've been playing around with varying levels of story in my games, I'm trying to hit a nice mark between story and gameplay, I might have pushed to far with story in this but I'll adjust with future games.
I really like the idea of being able to shoot one bullet at a time if less then 4 coins, if I ever revisit this mechanic in the future, I may play around with that concept.
Thanks for pointing out that spelling error, I'll fix it in the post-jam version of the game!
