-Not sure if this is intended, but my impression is that when the characters speak to you about "the quests", every now and then their speech isn´t very clear as if they themselves aren´t really sure about what they are talking. The Quest log in your diary, however, is very clear about what you need to do.
-No problems with the UI itself. However, the numbers of hearts for each girl doesn´t give you info about what kind of favors she will accept freely; perhaps a tooltip?
-Well, the game is incomplete, and it shows at certain points. For example, when you work with a girl, the option to do extra work and earn extra tokens seems placeholdery for me. Other than that, I'd say it is OK.
-Not sure if it is a bug, but in my game (I have used the same save file for the least 4 updates, possibly more, so it might be something in my end), there is ALWAYS a monster to be cleansed at the camp center. Drowning in tokens due to that.
As for suggestions, whenever I see Kate, I get the feeling that her content is not complete yet. Yes, she has a quest, but after you finish that and have your non-repeatable sex scenes, she might as well not exist anymore. No favor, no more interaction save for Garbage Day.
Now, of course a Councilor would have zero reasons to have sex with the MC for Tokens. However, as we see in Kate's quest, she (and presumably the other Councilors, too) is very horny due to the fact that there are no men in the camp. Therefore, 2 systems could be implemented:
1- Councilors orders: every now and then, one of councilors would drag you for some work: Do it right, and you earn some favor with said councilor (do wrong, get some sort of penalty). Reach a certain treshold, she would trust you enough to have sex with you and NOT be ratted out)
2- Nocturnal escapades: Since the Councilors can´t be seen "fraternizing" with the MC, he would need to sneak at night and go to their quarters, once there, the sex would have to be silent enought not to alert the other councilors/campers (perhaps a minigame?).
Well, thats all I have for now. Keep up the good work, and good luck.
