Just played this game for a couple hours. The concept is (afaia) unparalleled; the writing is really good so far, and I haven't yet seen these adult funny pictures. The strategic side of the game is interesting and pretty unique too.
However I found an exploit. This probably has been mentioned before, but anyway: when you visit Alexandria (Tiffany), you spend 5 energy on the action, but gain 10. So I managed to visit her on her campus on the first day, and now on the second day I can visit her indefinetely without any actions. Just spending 5 energy to gain 10 thus repleneshing this stat as many times as I wanted. So I guess I can max any stats and cards as long as the game allows me.
This (and the UI) doesn't make the game well made, but at least I can save my time from grinding.
