The sounds and visuals are spectacular. This game is super chill and relaxing. The puzzles are unique and really cool. My only complaint is that while the old buildings being randomized each time makes the game visually interesting, it can be hard to remember where to put the new buildings because it almost feels like the levels are being completely randomized even though it's only the models that change.
But overall, this is probably my favorite game so far (I just wish it was longer :P)
