It looks very nice. It's interesting to play. Nagging:
- camera shaking is very strong;
- the power of the jump is immeasurably strong;
- when you press down or up, the character shakes;
- the object "check-point for music" is on the layer (Z-axis) above the character;
- there is not enough charge indicator of the second strike (it is not clear when it can be used and when not). And it is better to put it on the right mouse button, and the often used hit on the left.
Thanks for the game. It was cool =)
