This game has some potential, but it got a bit obvious after some levels. I could simply run and finish each level without engaging enemies.
Graphics and music are specially cool.
It seems that I also found a glitch in level 8. After I completed the level, I was taken to a white plane with nothing on it. There was some kind of white bar in the bottom of the screen, and that was it. I walked a lot, reached the end of the white plane and fell to the void.
