Very impressive entry! I thought I would point out some MINOR improvements that I think could be made but over all this is great! I think iI would have liked a slight, minimal soundtrack. I did fall through the floor in the second sector. I think there is a way to improve the checkpointing, but I was really glad it was there. I would reset or run into a saw if I was in a completed sector since I knew it would bring me back to the center, maybe in that case it should respawn you in the sector so that you have to navigate back through. Seriously great work!
