Dead Cells just arranges a few pre-designed rooms together for each stage, doesn't it?

If it does do that, it doesn't feel that way. I never found it particularly repetitive.

To be clear, "a few" qualified the chosen rooms that get procedurally connected for each stage. I'm confident the pools of premade rooms are rather large, although I certainly noticed some repetition back when I played.
