At first I didn't get some things but after a couple of deaths I've started to understand the game better. It was a good experience overall and the game goes well with the theme. visuals are nice and combines well with the music. I think it needs a bit more of play testing to balance abilities though. And there is a small bug that makes the Act I label change to Act II permanently when going to the second act, dying and retrying, just to let you know.
Nice work!
