I enjoyed this game pretty much. It defenately stands out, it's not boring, the bosses were pretty interesting and gameplay was developing. The annoying thing was that the first boss you encounter, was at first furiating, as it took me some time to understand how to beat it. The story could of used more development and the ending was pretty lame.
The graphics are awesome, so is the soundtrack. Overall, great experience and worth playing. Problem was that, i quess it's a newgrounds thing, the screen was too small for the game. Some bars and menus were hidden.
