This was a good looking game with fun atmosphere and free movement system.
Fighting enemies was hard though, between managing shields and power and missiles, it was not easy.
Though the main problem I had what finding the way to the goal... I happened to leave the maze which I suppose was intentionaly according to the screenshots, though once outside, I suddenly was unable to move, or at least, the screen was not refreshing anymore to show my move as the only thing which kept moving was the compass which did not cleared itself between frames, making itself repeating.
And the problem is when I restarted the game (using the menu which kept working), the problem didn't stopped. (See the screenshot to see what I mean)
Still original and interesting entry though!
