Loved it! The controls were responsive, although the control scheme was hard to get used to.
It was challenging to get past the level before the boss. Felt like one of those old platformer games where the developer just tries to find ways to make the player rage quit (Which is a good thing for me) .
I managed to kill the boss at the end, but it bugged out so the boss just stood there with no health.
The art, animation, and music were well integrated into the game.
I had a lot of fun playing this game!
