Hoping to see more new updates for this game. I'd personally enjoy a downed system allowing the player to escape grasps at least twice before succumbing but if the grasp escape attempt fails twice it can lead to a game over as it is in the game already. You could add extra such as the protag getting impregnated but that's a more personal preference.
How'd I imagine it work would be the protag can be grasped no matter their health at random from npcs if they choose, or it could work as the lower your health then grasp attempts would be made.
Whichever you choose I personally would like to see cream pies, and status ailments affecting gameplay such as if you've been creampied while in a downed state and recovered from it, npcs can track you if you attempt to escape after being seen that is if there will be stealth mechanics and so on.
Good luck with development.
