Thanks for playing. Yeah, I kind of overscoped, and ran out of time at the end, and didn't get to spend as much time balancing and polishing as I originally planned. I did post an update on my personal website that improves the white bullet rate in most of the levels, which I think helps a lot.

The player collision is a little smaller than the player, because I was sort of trying to make avoiding the normal bullets a little more forgiving, but that also impacted the collectable bullets, since it uses the same collider. Maybe I could have split those up into two different colliders instead so I could control them separately, I suppose.
