Some ideas.
More protagonist emoji column.The existing perspective effect is insufficient.
More protagonist voice.For example: struggling and gasping for breath.And it’s different with a gag or not.
More restraint.For example: clothing with tentacles, tickling shoes, earplugs, noseplugs.
More clothes.For example: stockings, body stockings, pantyhose.
More emoticons.For example: ahegao, whites eyes, fainting, heart eyes.
More sex toys.For example: Urethral blame, Clit blame, tentacle, 搾乳器, 淫紋, Oxygen mask with aphrodisiac, nose hook, anal hook.
More sexual torture training facilities.Not just bundling, placing, or dragging for a walk, enemies can use various props to torment the protagonist and train them.For example: bondage car, 三角木馬, candle play, forced orgasms hell, edging hell, tickling hell, Machine rape, 匂いフェチ調教, foot slave, torture, 呼吸制御, tentacle abuse hell, sex slave brain wash, 浣腸.
Some professional vocabulary can only be expressed in Japanese. If there is anything I don't understand, I can reply to the relevant link.
I actually really want to participate in the production, but I'm not sure if I'm qualified enough and I don't have time at the moment, so I came up with some ideas.
Thank you for the game.XD
