This game has such a completed feel to it! I have so many questions and things I want to ask, but I see that you have given such detailed comments below, that I need to study those first.
Solid gameplay! Loved the procedural generation, and I wish you all the best in finding a way to hide the "next level portal" somehow better. Still, to be honest, I really liked being able to cheat my way through some floors :D
Well done!
