“Cool and clever puzzles with distinct sokoban mechanics, but an absolute waste of resources on overproduction. Aesthetically and narratively, this feels like a 2010 idea that took 15 years to manifest. The puzzles are dope and that's why we're here, but why do I have to alt-F4…”

“Funny puzzle game with some good writing. Laughed out loud at some jokes. Enjoyed the puzzles and got a bit stuck on some, but you can skip past some levels (not entirely sure how that works). I haven't finished yet, but worth your time if you like spatial logic puzzles.”

“Being bullied around was never so much fun ;) Clever puzzles which are often not easy but doable, bit much chit-chat here and there but it's amusing so that's ok.”
