What a creative idea! I also really really love the presentation - the line motive was great!
I do think that the controls could have been a bit better though: I think they should have remained fixed regardless of the player's orientation. My reasoning is that then you always know that W always jumps and A and D are always for movement and you get more accustom to how these controls work under different rotations
Great work overall! Really enjoyed my time with the game.
