Wow, this is quite a nice one! I like it quite much. The narrative is obvious the main focus here and it work quite well. The graphic is also very nice! I also like the idea of drinking tea calming thoughts, and as a game mechanic. Three different tea with different effects and also need to determine who want what tea is just a great use of it. Nice! I would like a good cup of tea now.
For the nitpicks, a big one would be the notebook showing in the wrong position most of the time, and I just can't get it back once that happen without dying. That is quite annoying. Speaking of the notebook, it would be nice to open the notebook else where, not just in the starting location.
Anyway, this is very well done! Keep up the good work!
