I like this game, but I find it confusing to understand the concept / dynamics. Each time a player does the "reunion" they start from scratch? Well, it seems like corruption carries forward each loop of the "reunion" cycle, but other than that it seems like everything is zero again at the start. I'm confused how to get more horny points or mood points for certain girls. Wish there was some kind of instructions / walkthrough.
The idea is: time is looping, but also the things that happen at the cabin are changing the past. For example in the first loop, Alex is a virgin. After you have sex with her at the cabin, the past changes so that you fooled around growing up, took each other's virginity and have been lovers for a few years before the reunion.
Horny points only last for once scene. Love points last for one loop. Some scores (number of Jennie's books you've read, Lina's nerve) are permanent. See the Help & Guides section on the menu between loops for more.
Nobody has any memories of previous loops, but there are hints that they were real. In some scenes the MC says "This seems familiar" and starts to remember a previous loop, but thinking about it gives him a headache, and then the memory is gone. There are a few other scenes with hints about why time is looping and who's behind it.
More than that will have to wait until we get more of the main plot.
The in-game guide (top button on the right of the screen) shows how many points each action gives each girl. By default it's hidden until after you try the action for the first time, but you can unlock the whole thing in the Debug Cheats menu if you want to.
