I 100% the game!
I probably cheesed a lot of puzzles by bringing everything from other levels and infinitely refilling the jetpack fuel to 4 (by making a snapshot where its at 5 fuel, then, every time you need to refill, making a branch where it changes to 4 and merging it with the current snaphot). But anyway, the game is great, I loved the mechanics (btw I never used revert, so I can’t tell anything about it lol).
