Fun visuals and theme, but difficult to play. Mouse aiming just does not work, not even with the DPI fix described. If I swipe my mouse too quickly, the game stops registering the input. You CAN play just on keyboard alone, but you HAVE to click the mouse to attack. If there was a keyboard key to attack, I would stumble my way through this, but as it stands, I could only do two levels. But it seemed fun, if you can get it to work.
