I really like where the project is going, and the music was very captivating!
I found a bug you may want to notice:
If you clear this gate, near the beginning, and die shortly after, I respawned on the outside of the playing field:
It wasn't clear whether or not a button or checkpoint was activated, and the second gate felt unusually difficult to get to with the spike on the pillar.
I assume that it is still in beta and that the submission would be far more polished, but either way I like where this is going, and it has great music.
