Overall, the idea is cool, but I think there's not enough feedback when you hit the boss. He has a lot of health, and it's unclear how much is left.
The music appears in random places.
At first, the controls are very strange, but then I got used to them and it was fine.
I also feel that the first level is the most difficult, and then the levels gradually become easier.

Thanks for playing. The boss definitely needs a health bar and audible feedback on hits. The levels need balancing for sure. The boss music was set to show up right before the boss spawns, but last minute timing issues pushed that off. Fortunately, all these things can be fixed rather easily after the game jam is over.
