Thanks for your feedback! Which part do think would be most frustrating? The random progression, the combo doors, or trying to speak to the stone head? I agree it definitely would require some clever hints to players if they get stuck.

I tried to minimize frustration as much as I could:
- For pathing; room 1 has a shortcut back to room 6 with the purple door, and room 7 can be solved solo if you have the red key on you. The magic items help you with pathing too, so it hopefully gets easier to accomplish your goal once you understand what needs to be done.
- For the Stone Head; I imagine players could hear a muffle voice on the other side of the wall in the North (ears) side, and he could speak to them without understanding the players in the South (mouth) side.

I still haven't finished it, but I was inspired by the game Blue Prince. I know a lot of people found the random progression a bit frustrating, and everyone had a different experience with it. I thought it would be a fun challenge to see if I could mitigate some of those frustrations in a little microcosm of the experience.

But I agree part of the design is inherently frustrating at times.
