Seemed like a fun game, but it is among the absolutely WORST games I've ever tried. There is no hint of a storyline beyond the background context in the intro, the shop system is horrible, with things spread out over FIVE diferent stores, and changing inventory withing those stores. The inventory system is horrible, especially if you want to give a girl a gift, since the item you want to gift MUST be among the top 8 pieces of inventory, because there is no scrollbar for an inventory that seems to contain dozens of items once you've collected them all. Chatting with the girls does nothing, except repeat the questions: "How do you feel about [other girl]","Do you miss something here?"
If you wish to ask one of the girls something, prepare to go on a manhunt across the camp for several days, because each girl can be asked AT LEAST 7 questions each, but they will only ever answer three at the time, then vanish to some other location, or altogether.
There is NO rhyme or reason to when you get an upgrade point. I have gotten upgrade points after skipping a day entirely. I have gotten upgrade points for doing nothing but aid in construction. I have aided in construction, skipped days, talked to the girls, gifted them gifts, upgraded buildings and haven't gotten any upgrade points. The game also cheats you out of upgrade points, telling you after a battle with a monster that you have gotten an upgrade point, but checking the menu, no points are available.
