Really good game! I absolutely love the take on theme and the concept is polished and well executed throughout. I actually felt motivated to keep playing, which is really good! I have some minor issues though. The controls feel a little off, mainly the fact you slide off the corners of edges. That makes it feel like the character is more slippery than they should be. Furthermore, I think some of the level design is a little cramped feeling and doesn't completely encourage the speed running mentality you are going for. Finally, I think the waiting time once you die is a little too long. I'd like just a quick fade and get right back into the game instead of a death animation, a fade and a door opening. Minor issues though, overall, fantastic game!
