I played on 20 January 2026 and finished in about 90 minutes
Gonna keep this short and sweet and without spoilers. I thought this was an immensely clever game, I had quite a bit of fun with it. There was one "rule" that I had check the hints on because it was unintuitive, but otherwise I think the entire game was fully solveable from the info that the game gives + your own intuition. I can't say I agree with the dev's decision to call it 0PLAYER, as I consider pen and paper puzzles(which this effectively is) to be single player games. Given the short length of the game, it's hard to not recommend it.
