The game has good potential, but you gotta fix the bugs where boxes can be on top of you and you have to shoot for a while to finally get them off, and I would recommend changing the "jump" and "shoot" buttons over. That last part was a personal preference but I think it's a global preference.
Menu graphics need a touch-up and there should be a prompt as you hit escape because it's just a sudden *poof* and you're back at the menu. I'll give you 2 stars for the game itself and half a star for the fact that it has controller support, although it shouldn't be the biggest priority, I'll admit.
