Not too shabby! It was a pretty nice experience battling it out with the boomerang through the enemies. I did feel like the difficulty spiked a bit too early with the shield guys as they are very frustrating to fight. Even when I had the great idea to throw the boomerang past the shield guy so that they would get hit when the boomerang returned to me (which I'm assuming was the intended way to combat them), there were just too many shield guys crowding around that just made my boomerang stop dead. Maybe ease the introduction of those guys with just one or two at first, instead of dumping a group of five of em at you when you first see them. I was hoping to be able to maybe buy some items to combat them, but money comes at you so slowly that it became a real grind. With some elements like music and other effects to add some pizazz and a better difficulty curve I think this could be really fun as the boomerang has a lot of potential for interesting combat scenarios!
