I'm very new to this game I have questions can you answer if you have played enough pleae?
First of all any tips?
Can I date all the girrls at same time?
What happens after I get caught cheating?
What happens if I skip a date or event?
this is optional any save file with max stats at the start?
I strongly recommend the wiki like ArDZer said. To quickly answer those those questions though:
Wiki
Mostly yes, but some women will catch on to you cheating if you fuck someone else too often and some will find out you're cheating though story events.
Usually the cheated on girl will leave the game.
LP penalty for missed dates. Some events will just repeat at their next available time, but some story events have consequences for missing them.
I'm sure there's something out there, but just play the game man. There's a in-game cheat menu to adjust LP and KP. I would not recommend immediately having LP at 100 without without going through their story lines, because every time you go through a story event their LP maximum resets to where it should have been for that point.
