Thanks, glad to hear the gunplay feels good since that's the main thing I wanted to get right.
I'll have to check out the import settings for the music and make sure that its setup to loop correctly. I'll definitely try out your suggestion for falling projectile attack and see how it plays, should be fairly easy to implement the change. Also the more I develop the game the more I think upping the gravity like you mentioned would probably suit it better, since you need to be able to quickly dodge attacks in a boss rush game. Platforms ended up being a bit hacky due to time constraints, but I'm planning to make it so you can jump and drop through them so they should be easier to use in future versions.
