I don't know where to start. I think people have said it better than I have, but this is a really wonderful game. The writing was well done enough to have me hooked onto it, and honestly is my favorite part of the game. The gameplay with the puzzles, which was very clunky and froze alot (had to wait alot), was quite fun to figure out.The art/style the game has was very pleasing to see and really added to the mood of the story. The music and sound effects were also a great listen and really did contribute to the tone. And of course, the whole yuri aspect was done in a nice format. Not perfect by all means, I do have some nitpicks and issues with the game. My biggest nitpick would just be the puzzles being very samey, or following the same formula (A example of this would be the "push two boulders for both to pass through").
I don't how else to describe everything besides it being great. Besides that, I really enjoyed this game and it has become a favorite of mine next to a few others, in terms of writing, so far that I've rated.
On a side note, the game does break on browser when you reach the ending. Got distraught over this, since I was invested, but I downloaded the latest version to see the ending . But man does it suck having it be technically unbeatable at the moment without downloading anything.
