Sir, this is "amateur" game development. "Professional" game development is a few doors down.
Seriously, the only complaints I can think of are (1) my mouse cursor didn't automatically hide when I plugged in my gamepad and (2) pressing A while a character was talking skipped that line, instead of filling the rest of the text in. I absolutely love character action games, but I've always thought there weren't enough 2D ones. This is basically my dream game.
