I know. I watched the first two days in the mature girl's route and in the childhood friend route but I was spoiled on certain things even before that. I just wonder if it's as complex as Kimi to Kanojo and will keep track of ten years later.

People already dug out all the info contained in the game's files, and I'm pretty sure there's nothing that happens if the player does some random thing or waits a certain number of hours (not counting the secret good ending). There are tons of hints toward his next VN though.
