Alright everybody with the questions, here are your answers:
Question: How do I have sex with/start a relationship with (insert character)?
Answer: See the folder in the game called "HELP AND WALKTHROUGH"? Inside of it are painstakingly written help and walkthroughs (go figure). If you're having game problems, consult the detailed and painstakingly written walkthroughs rather than showing up here looking for somebody to hold your hand. If you're playing an adult game, you should at least try to act a little bit like an adult.
Question: How do I save in this game? How do I quit?
Answer: Use the UI. Besides the autosave feature that should prevent you from having this problem in the first place, you can just pull up the phone (after getting it in the beginning) by pressing W, then just go to the disk icon and save.
You need to quit the game? Close it like literally anything else.
Question: Will this have an android port?
Answer: No, unless somebody wants to rebuild the whole game in RPG Maker MV, it will never have an android port. RPG Maker VX:Ace games are fundamentally incompatible with android and cannot be natively packed into, or read from APK Format.
Question: (insert dumb question here)?
Answer: Be an adult and figure it out.
