This is a great entry! I didn't encounter much anomalies in my playthrough. i think I only saw 1 or 2 rooms that were anomalies. I think maybe instead of a random chance for an individual room to be an anomaly, there should be a fixed number of anomaly rooms (say 3-5) and you just scramble their order of appearance.
The visuals were awesome, but the FPS was quite pathetic for me, and I would consider my computer to be pretty decent, so there are definitely some optimizations to improve.
