Hey thanks for playing! I'm working on a game jam this month so not much time to update this one, however for a point building strategy I'd recommend building up Agility and Atk a few times, then buying Fire Punch. Clothing gives you the most points outside of doing damage, so if you can break her clothes consistently you'll get more points each round.
The game is designed for you to lose a few times at first until you get enough points, so keep at it until you achieve horny victory! >:V
