The game couldn't grab me. It's very repetitive, with many islands being trivial or something you've already solved several times before. I thought the open world design would be cool, but it's frustrating to navigate once you start wondering if an island you see is even reachable from where you are, or if it's impossible and you're expected to go somewhere else. There's no obvious path to follow or anything to tie the experience together, you just randomly explore but aren't rewarded with anything special (the first few exhibitions are fun but it's the same joke every time).
Play Cosmic Express (from the same dev) instead.

Very clever puzzle making. A lot of content to be discovered

Only minor issue I have is that some of the later puzzles (especially collecting snowmen) can be unintuitive, though that may just be my small brain
