Thank you for the comment! I agree that the secret route is too difficult at the moment, and a fix for that (in the form of another difficulty setting) will be coming in the next release
The planner (and similar mechanisms) are a bit more common in stat-building games, which this kind of is, but someone else also said it interrupted the flow of the game. I think there's not much I can do about it at this point, since it's so integral to the gameplay, but if there are things I can do to make it more obvious which actions do what, let me know!
Adam isn't flirting with you... he's just very comfortable around you, including physical affection. He is not a route, and you can't date him.
