Full disclaimer: I've only solved two rooms, and 2 others I "solved' but needed to look up the solutions because of, quite frankly, some low-quality polish on the game. That being said, I'm still going to recommend this game because those looking for tough brain-teasers using 3-dimensional spaces will still find some enjoyment out of this. Also, I will not be finishing this game because I simply cannot be bothered to fight with the poor quality-of-life that is walking around this game.
Spoilers ahead

The first room does a nice job of setting some expectations for the puzzles to follow. There's a riddle/puzzle presented to you in common-enough terms, but in order to push through to the "actual solution", you'll need to look around the room(s) for hints, contextual clues, and specific info.
Foyer was okay - I solved in about 5 minutes, but noticed that the controls and limited perspective hindered me a bit. Not enough to say "the puzzle is impossible", but enough to say "I really wish the room-specific hint/clue/key to solving the puzzle was easier to physically look at in the game's viewfinder". I pushed past it, however, cause it was intriguing.
Room 10 was the astrology room. A unique puzzle, fairly straightforward, except the riddle presented one of those "it COULD be solution 1, or it COULD be solution 2 - you'll just have to brute force the solutions you think it is and find which one is right :D " type of solutions. Really wasn't a fan of this. The Taurus looks like he's dancing, a.k.a. "side stepping", but nope he's not dancing, he's actually "making water vaporize"?? It made way more sense to me that the goat-themed animal (a.k.a. related to satan a.k.a. related to hell, fire, boiling water, steam, etc.). Again, this puzzle wasn't enough to make me drop the game, but I was genuinely frustrated because the statues are hard to get a good look at because the player character is really low relative to all of the objects/architecture of the game. I get that this is to give it a "whimsical alice and wonderland" type of feeling of weirdness, but it was really impacting my enjoyment of looking around for clues/hints and solving the puzzles.
Room 9 - I doubled back to the chess room. The sudoku hint was nice, and after a quick leap of logic the solution to this was pretty apparent, so I took some time scooting the statues around for the solution. Nothing ambiguous here, very nice. Struggled a bit with the statue readability though, which added to the whole "this really needs a quality-of-life update and polish so I'm not fighting with the art direction of the game". Was a bit annoying, but again, not a HUGE deal.
Room 7 - This is where I simply gave up. I tried a few things, noticed some hints and clues, but this room is where it really hit me with "okay, simply navigating around these rooms is slow and cumbersome, and I'm CONSTANTLY fighting against the camera perspective to just have good readability on the puzzle. I'm spending 50% of the time thinking about the clever and unique puzzles, and 50% of the time saying "why can't I just alter my camera field of view? Why am I so slow when I'm sprinting? I get why the rooms are compact and a little maze-y to navigate through, but I'm spending 10 seconds "running" between dials just so I can spend 1 second tinkering with a dial that I'm not even sure I'm pointing in the right direction because the readability of this puzzle is so freaking bad.". This room completely soured me on wanting to complete the game.
Bonus frustration point: I looked up the solution to the cartography puzzle (there's absolutely no hint of progress while you're doing these puzzles, so the whole room is 'all or nothing') and not only was one of the compass dials supposed to be a really specific number, but there's a hidden dial that relates arbitrarily to the thermometer in the room. I spent maybe 30 minutes changing the compass dials around the room thinking the thermometer would increase/decrease relative to the accuracy of how close my compasses were collectively (to allow a margin of "error" with each compass", but... nope, there's just a random compass you need to do a small mini-puzzle with that completely flips the whole room's concept on it's head (you aren't pointing to a pole any more, nope! for this one specific compass you put the compass dial at "negative 45 degrees" because that's the temperature it's at!! Isn't that a clever twist???").
Again, I'm not going to "not recommend" just because I wasn't able to solve the puzzles and had a frustrating time with the controls. This is DEFINITELY a game where a certain type of player will ABSOLUTELY LOVE all of the puzzles, twists, and quirks this game has to offer - it's just not for me. I love brain teasers, but I'm not going to fight the basic art direction, controls, and perspective for 7 more rooms just to look up the solutions because every room has some weird ambiguity to it in order to trip up the player.
