1. The starting art gave me a high hope that the actual game will have the same quality, but it turns out to be very simple. Maybe you would make the ground smaller and charcter bigger.
2. I did not realised it could be a rhythm game until I saw another player's comment...
3. I don't see health bar, and doesn't seem to have win condition? The mobs just stop spawning after some times...
4. No restart button...
