I'm noticing something weird with some of the puzzles, i'm not sure if it's intentional or to make the playtime of the game longer but there's quite a bit of puzzles where there's times where you have to brute force it to even get the answer to them. 'expand' and 'rotate' have this problem specifically, all you can do is sink in time to even get the answer for them, even with the hint's provided to you.
