It's definitely an interesting concept and it looks and feels good. However, as I'm usually bad at platformers, I found it really uncomfortable to be forced into going at a pace I'm not happy with. Overall, nicely done!
Yes , I acknowledged that such elements might deter people from the game, but it fits the theme so seamlessly that I had to expand on it , and make it into a difficult platformer (which I still haven't optimized my routes even after a hundreds times).
