Cool game! I really liked the movement with the mouse (instead of having a keyboard) and the cool combo system!. Some inputs:
- I think the enemies have a bit too much lives. Especially the big ones take quite long to destroy, which makes the game very hard!
- If you balance the lifes of the enemies I would add collision between the player and the enemies. This brings another element into the game (dodging the enemies).
Congratulations to a really cool game! Had fun playing it!
