This game is amazing! I love the art style as well as the music design and the interpretation of the theme! The character feels extremely responsive and it is really fun to move around and use the movement mechanics!
I also really enjoyed all 3 of the boss fights! They were really well design and they all felt unique in there own way!
The only thing that I didn't really understand was what the power up did in the secret room, though I totally understand that due to the time limit, there was maybe no more time to implement something.
Overall an amazing game, and I would love to see it eventually have a full release! Great job!!
