A delightful little hybrid of twin-stick shooting with platforming and physics-based puzzle mechanics. Moderate replayability, too, thanks to the varied challenge objectives accompanying each level. Until roughly halfway through, I would have docked some points for the interminable stuttering (a serious problem for a game where timing is important) but I resolved the issue by changing Anisotropic Filtering - a low-impact option in any other game - to a lower setting.
