Solid gameplay with a good power up system.
Art was good, I enjoyed the last boss design a lot.
In my humble opinion, the game pause downgrade feels awkward, it's not really a downgrade, it's just annoying. The others upgrades/downgrades felt kinda right.
I've really enjoyed the room where you have to dodge and survive, it was quite fun.
Overall a solid game, I had fun playing it. Good job!
