Thanks for the feedback, you're not alone in struggling a bit on the last challenge!
I added a difficulty option in the start menu that makes them chase less aggressively for now. I'll look at organizing them so there are just fewer on easier difficulties in the future.
Truth be told, I personally found the main difficulty was not being able to see even a quarter of some of the larger rooms on screen. Had more than a few head on collisions from that!
