As a big fan of ghost runner, neon white, and mirror edge, I must say I really like this game, the movement is fluid, the entire vibes are so cool, and there have lots of parkour shortcuts!
Not really sure how can you perfect the movement system in under 48 hours, but you did it with flying colors.
And, I like the twist of Roll Reverse in the end. Will try to finish all levels in under a minute as a challenge when I'm free, for now, here is my time!
