I'm not sure if I get it, I tried to solve the 2nd puzzle (the one with R,G,B) with R on my first playthrough and B on my second playthrough, and I got different results, but the game just hard closes when I exit that room.
Hi ! Yeah, we intended to make the player leave the labyrinth on the "good" ending and a fade-to-black for the "bad" ending but we didn't have time so we just made it so the game closes when the player tries to exit the room.
