The way (you) is written in the description was a good way to hint the game will interact with me the player but I wasn't sure what to expect (creepy, funny, something else ?).
Well after playing it I can say I really liked how it's done! Not understanding what Amelie is talking about scared me just enough without going full psychological horror, it felt deserved to finally get an explanation along with them getting their good ending. Glad I helped those two~
Not sure if it's intentional but sometimes I felt Amelie sprites were looking at me instead of Michi. And at the beginning of the game I immediately restarted and named myself Michi (and Amelie) to see what would happen, it's a nice touch you thought about that lol
