That's likely because the beat window to hit it is fairly generous - it could be that I add a delay where clicking too early means you can't shoot that beat, though? I did trial having your bullets be on-beat too, but it felt too unsatisfying with how projectiles flew, and having to lead your shots and such.
Sound settings and such are gonna be the first thing I work on post-jam, it was the one thing I wish I could've gotten in-game in time!
Thank you for playing!
