This was a fun but somewhat frustrating experience.

I think the "open world" structure of the game is quite novel, and makes it stand apart from it's predecessor, Cyberbox. A lot of the puzzles are quite clever, and I very much enjoyed making my way around the mansion - searching the perimeter for secret entrances and catching glimpses of where you're going next in the corridors.

There's a pop-up at the start that says that if you manual save at the wrong time you can absolutely hard-lock yourself. I was very cautious so I wouldn't get stuck, but I definitely had a few close-calls. For how easy it is to brick your save, the levels make it quite easy to do so.

This is by far one of the hardest Sokoban puzzle games I've ever played. I got stumped in one particular section near the end of the game for 45 minutes (I think it was a bathroom 7-8ish puzzles in from the left-hallway?), and with no way to save (the browser's fault), I had to call it quits without seeing it through :(

I hada  good time overall, it definitely made me use every last wrinkle of brain, but I just wish I'd been able to finish it.
