Thanks for the great feedback!
Yeah, in hindsight, having transitions to other rooms and walls that stop you be the exact same, especially for the first instance it happens, wasn't the best idea. Well, regular sight should've caught that sooner to be frank.
Now, I'm having horrifying visions of people hugging the outer wall on a puzzle they think is impossible, not knowing any better and getting frustrated. I suppose this perspective from the player is something I overlooked.
Anyways, I'm glad you enjoyed it!
