I got jumpscared exactly once lol. I think the AI handles decently well, in the sense that that once you hear it, you have a chance of actually escaping from it - instead of it being an immediate instakill, as Ive grown accustomed to expect with more primitive AI implementations. I think the coinflip is okay, definitely a jumpscare moment and wondering why you're still alive - could probably have a better lore reason or something. I liked the wall illusions slowing you down, I like the shaders, I like the outside area (although I didnt realize they were all connected at first) and I like the overall lighting of the interior maze.
I think you put the monster too close behind a wall, so your heartbeat actually gets triggered on your way to the exit screen after youve finished the game.
Also your exit easter egg was a little unclear, I just ended up jumping off.
pretty fun pretty solid little challenge maze congrats on the release
