I have to agree with the others, even for a demo the grind is way to big, even more with fixed incoming events that spends time of a day. It takes visiting the bar 4 times 3.680 Money to just level Socialising up to level 2. Than comes the money factor that you need to spend on your sister, on groceries for reliability, for gifts, for rent, or just events its too much with limited time. So you need to level up stats, romance and make money. The time aspect can only work if the dev makes it so that you have to focus on one girl at a time but even like it is atm its not possible.
Just look at other games like Hunie pop, you have to be able to ask questions AND be able to spend time with that girl. It makes no logical sense that it skips a Time of the day just to ask "What is your favourite hobby". And just like Hunie Pop has it after you know something about her you should get asked questions and get +Lovepoints for knowing her.
Putting the obvious problem asides, the Art is really good, the basic concept is very fun, it has great potential i really hope their will be some changes to it.
