I am in the brainstorming process of the the next umichan game that follows Maiko (or some female character, still thinking about it at the moment.)
Mostly the technical stuff.
Even though there is a UMCS at the moment I think I will call this UMCS (classroom shenanigans). and plan to have this take elements from both umcc and umch that seem to work well.
some of the stuff i plan to use is listed below.
pattern match hentai minigame
modified stress system from UMCH
trouble system from UMCS
friend system from UMCS
money system from Umichan Sentoryu
and the complement system posted below
feel free to post suggestions on what you would like to see make a return.
