Very cool game! I love the idea and everything is so polished. Honestly, I'm still amazed by the full song and full voice acting. Overall, everything was great, the game mechanics and level design were very nice, and I had a good time. Unfortunately, whether at the fault of my low-end laptop or a bug (I assume the former), my mouse sensitivity was insanely high (even when turned all the way down, it was still quite fast). It didn't really detract from the game experience all that much, but I figured I should mention it.
Again, great job!
