Yesterday I played a bunch of the game and got pretty far, possibly the last level judging by the level select? I believe I even exited to the main menu and the Continue option was available, and did exit numerous times to level select. However upon booting the game up today (on the same computer, so Steam Cloud is out of the picture I believe) the game no longer lets me Continue, forcing me to start a new game. This sucks. Any solutions? I'll probably speed through the puzzles but I might just give up ha...

Every time I try to launch the game it immediately crashes back to the Library page. Anyone else run into this/have a solution or ideas? System: Win 10 Ryzen 3800X 32gb RAM EVGA 3080 GPU

Am I the only stupid person who thinks this game is ultra hyper mega hard?! It's rewarding when I understand the deformation rule, but after some levels, my brain becomes a bowl of spaghetti. Still, I want to play this avoiding tutorials. And, yeah, I know a hint button shows up at the upper left; very useful at times, at times....

Hi, I've solved Octagon 1-8 and got their achievements, but I still don't get the "Octagon" achievement itself. I thought maybe I needed to do something after solving them all, but I just solved all Decagon's and got Decagon, so I think I should be getting Octagon too?...
