This is a great puzzle game! I like the art and presentation of the game. The music is very relaxing. The ending is pretty surreal as well.
Regarding the puzzles themselves: They can be a bit difficult, but that makes solving them that much more satisfying! I had to use the optional hints after a bit of trying to connect the dots myself and getting a bit stuck. Even though I used the hints, I still felt that I had room to “solve the puzzle” rather than just be outright given the answer in some cases. I think it’s a bit subjective though because I can totally see some hints straight up giving the answer in some cases, which may not be to everyone’s "hint" tastes. I personally thought it was balanced fine though. There were only two puzzles I had to look up the solution for.
Again, this was a good game! Definitely go into it blind if you’re interested!
