Very good but with certain annoying moments.

Descends quite quickly into painful trial and error. You can get out of certain situations only by dieing and that should never be an option in a good game.

Mix of mouse and kbd controls is never a good option. Its disorienting, in FPS it stands to reason, but in basically 2D platformer its redundant. Otherwise, kinda fun, with all the cutness and gore.

Much better then I expected
