I have some ideas that might interest the audience.
- Two NPCs could try to tie you up, making the minigame a bit more difficult. For example, while one is tying you up, the other could start groping and kissing you, making the minigame less effective.
- Erotic toys. I know there are vibrators, but there could be another bar, a pink one, that represents orgasm. If it reaches the maximum, the character orgasms and is stunned for a few seconds. (The erotic toys could be: dildos, vibrators, clamps, straps)
- Another restraint method using duct tape. If you tie up the NPC's entire body, or if they tie you up with it, you'll be bound like a mummy, completely immobilized and blindfolded.
That's all. ^^ Thank you very much for your attention.
