Thanks, friend! I'm glad you liked the minigame ^.^
Obviously there will also be vaginal sex, your trust is well placed ; )
For the rest there isn't a real limit... the only limit is the player's time and skills. Although I must admit that making more than 4000 points would not be useless because this is the threshold to unlock the lv 4 affinity with Ajoora. If you think that killing an enemy gives you 1 affinity point while a boss gives you 100, you understand how important it is to have sex with Ajoora to improve your affinity with her. But we're talking about the full game here...in the current minigame scoring is just for individual glory XD
