For now, the powerup indeed exists in the game (in Bowser Castle level). This happen 33% of the time you enter in the club. Just use the toilet in the middle IF you notice the right door is locked up. NEW SCENE: Luigi Gloryhole scene! For it to happen, you have to find Luigi in the bathroom of the club in 6-4 level.
Blargh will be doing adjustments in order to make the nymph scene more adequate. But! 'normal' and 'nymph' scenes will be 'akin' (mostly, if not all, identical). NEW SCENE: Final scene (Bowser and the princess, then Mario and Shadow Queen) in Bowser Castle level by Blargh! It has three different moves: virgin, normal and nymph princess.
Thank you again and again for all the support! I do have a plan to leave my job and prioritize more projects, but I told myself I'll only do this if I complete this game and starts Wonderful Sonja project! In the meantime, I was refreshing my mind with other games as well (just for curiosity, 'Adventures of Tara' - RPGmaker game), so I could get more ideas and restart my brain. (INFO) - PHEW! What happened? Just my job 'killing' my nerves and time.
