Mofu sensei wants to add more ways to play,he may consider these suggestions,as long as it is not too R18G or contrary to the content of the game settings.but at present, he is developing game alone and he only can do that in his free time, so there will be many difficulties.and you mentioned Messy,I like his works too😆,but updates too slow.
I believe Mofu sensei will bring more surprise to us,but he can only develop game in his free time,therefore, some complex contents which you posted may hard to be realized,please understand.But it's okay,because if you like a game then you will naturally have ideas about the content of the game,it's not bad😉
