With how much we have nerfed Level 3 to make it more enjoyable for casual players it feels quite plain to those who have more experience. To me a good amount of the games replayability comes from two things: speedrunning, and difficulty. While I can get on board with making more difficult levels such as 3 easier in the casual I feel as though it could be debated to keep the original difficulty for Purgatory mode.
This being entity on all floors, less item drops, needing two wires to fix the catwalk, and any other nerfs I may have missed. I feel as though a big part of the Purgatory run's success feeling is the accomplishment of completing a harder difficulty and while it is still harder only having one life, I think we could keep original difficulty of the levels for Purgatory runs. Especially when it affects things such as achievements on Steam and roles in the server.
I am open to any criticism on my suggestion, so feel free to respond to my message if you have any questions or criticisms for me. I appreciate your time in reading this.
