Decent, but not amazing.
It has a interesting concept, but its lacking a lot of things. Its glitchy for one. And not minor glitches as everyone says, pretty game breaking glitches. The movement locks up, the games FPS is inconsistent, and what bothered me the most was the sudden spike in the difficulty curve at the first boss. The game went from a walk in the park, to insanely hard, and I found myself grinding levels on level 8 for awhile before I managed to beat him. Maybe I was just doing something wrong, or the lag of the game was screwing me up to much, but there is usually something wrong in a game when a boss is seen more as a roadblock, then a challenge. I got past him, but still, I felt I spent to much time on the first boss grinding levels.
