now that I got it working: I like the idea, it feels good to play and requires some strategy. the tutorial is nice and clear, though it’d be even better if you could skip it after dying and replaying. listening to the doors is kind of pointless, since if they don’t require a key you can just walk through, but the chests and enemies work well.
I don’t know if this is a bug or I’m doing something wrong, I’m stuck because there’s one locked door that I can’t open even though I have a key, and one passageway that I can’t walk through/there’s an invisible wall in the way:

also the first time I played I somehow went back to the first room just as the tutorial started, which softlocked me:

bugs(?) aside I really enjoyed this, I could imagine it being turned into a full length game
