Thanks for playing our game and sharing your thoughts! We're glad you enjoyed the mechanics and found it to be a nice, quick experience. Sorry about the issue with getting stuck in the walls, we’re working on fixing that. Also, the other sounds you make, like running and stepping on metal, actually attract the monster to the noise source, so we have a bit of that mechanic you mentioned, but we’re definitely working on improving it. Thanks for the overall feedback! There will be an update coming shortly with a lot of fixes and some new content, and another one this weekend with a new "secret" ending.
