That catchy music!! Love that music. The game itself is swift and addicting, though I'm not sure I like the overly dynamic screen movement when you move the mouse. Also, the thing easiest to spot on the bats seems to be their HP note, feels like it'd be more fun if they're a slightly bigger/more noticeable target. But overall, a very catchy and fast-paced game, and very nice combination of clean pixel graphics and dynamic lighting. Nice work!
