If I get the mechanics of the game right, there will be 4 time periods per day: morning, noon, afternoon and evening. There could be also later possibly night. Some actions seem to not to actually count, like asking the barista for the wifi code, whereas asking for the library Id does.
It looks like there will be attribute points, as Fitness if you work out, so I believe that there will be others, like Charisma or Intelligence that may come up later. As for the (not so) romantic encounters, I understand that there will be either actions to unlock or relationship points with each (female) character.
It seems that the MC will have his hands full very fast as there are in this version alone 2 main quests and 2 possible side quests.
The only thing that bothers me a little is in the choice of models. Why does breast size need to be proportional to body size ? Also it would be nice to try and work on the teachers/moms figures. All the characters almost look the same age. Some nice expression wrinkles may be not only more realistic, but it could also make them otherwise sexy too. One last thing, why do the mothers seem to be always taller than their "adult" children?
As for the morning class being almost empty. I agree with
@ThunderRob on the necessity to make it look crowded, especially the first day. I remember my days at the university where classes were overcrowded before Halloween and started having less attendants afterwards.
Anyway I'm eager to see v0.2 and how the story evolves.
Keep up the good work.
P.S. Will there be a phone/pda to keep track of the stats/logs ?
