Hmm... well... I'd kind of like the Rocket Turtle to be an enemy instead of a boss. It's in the enemies section, but you have to activate him like a boss. Oh, and I think the rocket turtle flies away too fast... you need super fast fire in order to kill him. I'm not sure if you could fix that or not though. It'd also be nice if the Tweedle Boss would actually be able to be seen when defeating him. It's hard to tell where the boss is when he's invisible. I'm not sure if you could fix that or not though.
