First of all, I LOVE the artistic direction and your use of color in this jam. I also thought you had a very creative use of the limitation. I hadn't thought of it, but "fighting yourself to stay awake" is definitely a great interpretation of the limitation. I don't think I've played a game like this either.
That said, I found the game pretty difficult. I was speeding to ram myself into a table and still didn't really make it. I think you could easily expand on this idea and make a great little game by tweaking the difficulty balance and adding more detail. Congrats on a lovely entry!
