Fundamentally, the design choices for this game aren't great. I'd guess this is an amateur dev just having fun with a side project.
Honestly this doesn't need the visual maps and walking aspects at all. You could uncouple that from the game, just make town into a menu, and the game would be stronger for it. By design it really wants you to just go between fights and slog through those.
Combat is a travesty. You spam Charge Up until you're out of MP and then use Concentrate, repeat. The long, boring combat sequences are essential to the game functioning though, as without enemies spamming molestation moves you never see any CGs and you don't develop any sexual stats. Given enough fights, enemies gradually develop the ability to actually have sex with you through normal play. This should be torn up and rebuilt from the ground up.
You can resize the game by pressing F3, but don't do this. It's somehow worse than the zoomed out view.
You can actually have children when pregnant, but it's also worse than you could ever imagine. If you become pregnant in a fight, and the fight lasts long enough, when you defeat that enemy the child is born and full heals the enemy. Your new born is now the enemy and the fight takes twice as long. Yay.
Edit: Also do not buy the buff items. They do so little it's pathetic. They seem to give 1~2 strength each, so you'll go from 440 to 441 strength. Fantastic.
