A very interesting story and puzzle orientation.
The story, art and music are all fantastic and well put together. Lots of retrigger-able tiles though, I've got the feeling you're not supposed to have the characters keep commenting about the sad garden or the out of place door. Some of these tiles can even be used to max out Yukari's Boundary again and again.
Also I read there are four endings but only found two of them in spite of all the possibilities I could think of. Endings guide when?
I included this game in a Jam showcase, but it's too long for me to fit an entire playthrough:
