This game is really breaking new ground. Among Twine games, it's remarkable for both using extensive beautiful graphics, animations, etc., but for also being long and puzzle-y.
You play as a rabbit in a warren of other rabbits, but something truly odd is happening. As you explore more, you uncover an entirely new setting.
A few of the puzzles seemed fussy, and I wasn't completely emotionally invested in the story, but this is a Twine game I can strongly recommend to those new to Twine and those experienced in IF.
