This is a cool rhythm battle game. The use of different characters with different playstyles was a nice touch. I have 2 criticisms for right now:
1. It doesn't seem like the Marine can recollect the bullets he shoots. The game tells you to recollect them whenever you try to reload, so I thought you just had to reload while standing by one, but it doesn't work. This obviously makes the Marine weaker since this takes away his ability to attack or change up his attack loops and there's a period of time where his bullets are no longer a threat until they loop back.
2. AI Crusaders in Deathmatch become AI Marauders instead.
