The audio quality isn't amazing, for the voice work, but that almost adds to the charm here. This is a really meta spin (snort) on the Game Jam theme, and it works really well. As others have said, I get strong notes of Stanley Parable here, and I feel like I'm going to have to come back and check it out again to find whatever hidden secrets lurk here.
The first playthrough was certainly something - and the fact it just abruptly ends with zero fanfare each time is really funny. I could see a joke being involved with it just cutting the narrator off midway through, in a meta fashion of sorts, before booting back to the main menu.
I'm going to have to dig deeper and find some more secrets here to unravel what the wall markings mean - this one's simplicity feels like a mask that's hiding something more within.
