A very interesting game, I must say! Unique concept indeed. I'll try to be as spoiler free as possible, if people who haven't played the game read this, so I may seem quite vague at some point, but I'm pretty sure the game's creators will understand pretty well what I'm talking about haha!
The art style is very sweet, and I love the characters' expressions. The setting is nice too, though it would have been nice to get to know it better, but well, the game is very short, so it makes sense we don't see that much of it.
It took me a while to understand the game's gimmick about the endings, because I started with Jeremy's route, and there was an error if you choose to tell him he must have nice plans or something like that instead of talking about grades. I was able to "ignore" the issue, but I was worried something didn't trigger, locking me onto one ending. Fortunately, I've tried the other characters later, and it helped. Still, I'm curious - does the game have only true and bad endings, or can I find a "good" (or other) one too, somewhere? That true ending was too heartbreaking, oh dear!
I was really surprised at the explanations at the end, though. When going through the boys' routes, I was pretty sure that what happened at the end was because Kale wasn't convincing enough when going back to the dorm and because of the "failure" that happened. It was very interesting to actually making it the opposite.
