I don't know if anyone will care about the puzzles, cuz you can just skip them, but HOLY SHIT some of the later puzzles are bullshit.
Like, the basic idea and rules of the puzzles are neat, but holy fucking jesus can it get frustrating, because it is ENTIRELY RNG dependent, since the game will keep spawning 1 squares until one of them causes a combination, and the RNG loves to dick you over and spawn one in like, the 1 place you don't want it to appear in. You can do stuff to mitigate it, but sometimes you really have no choice other than to just hope the game doesn't fuck you (and not in a good way). And, since the gold blocks are also RNG dependent, sometimes the game will just straight up give you a layout that is literally impossible.
Emma's puzzles (the rabbit girl) are especially bullshit, since pretty much whatever you do, you're almost guaranteed to have a 1 block pop in and immediately gridlock you into not being able to do anything. Like, the only way to beat those levels is to have some incredible luck with perfect spawns and a perfect gold block layout. I'm pretty sure the devs didn't even test to see if those puzzles were beatable, because it's often literally impossible most of the time.
If they had like, made it so only a single block will spawn when you make a move, or heck, even let you choose where to place new blocks until a combination is made, that would have gone such a long way to making the puzzles both doable and maybe even more enjoyable and tactical...
But no, instead I have to try over and over because the RNG keeps dicking me, which really sucks, cuz I'd rather it be the cute furry girls getting dicked.
In summary, skip the puzzles, they're not worth the headache. ¯\_(ツ)_/¯
Edit: Here is exactly what I was talking about, you literally CANNOT solve this, there's not enough space to build up a 3 block on the right side, and you can't restart a puzzle easily, so I just have to move pieces 'til I lose on purpose. I am flabbergasted at how bad these puzzles can get.
