I enjoyed this game thoroughly. I can't speak for the other reviews, I had no problem with controls and there was nothing really super glitchy. what we have here is a game designed to play like a NES era platformer. The influence of Cave Story on this game did not go unnoticed. The engine physics is rather fluid, but I actually like that, the action plays as a cross between Gunstar Heroes and Ninja Gaiden. The art design aesthetic and soundtrack are top notch. The game does leave you wanting more. I will easily play through again a couple times, unsure on multiple endings or secret endings. It's 4 bucks, there's a lot of bang for your buck in this game. Would easily spend on an expansion pack or buy designer's next game.
