also, finally saw this so let me respond as fairly as possible. don't know if it's because you edited or not, so aint going to be rude.
crimson high still is a highschool, or rather form of it. it seems to be a form of academy that's meant to finish out your last year or 2. those actually exist irl, generally tied to a college. there are some that aren't as developed and do look younger, however none are as exaggerated as anything he likes. again, not accusing anybody of anything because im well aware how many games are set in high school without even that caveat, and nothing more than all charters are 18+ disclaimer
same is generally true for most of your games. while some are somewhat underdeveloped and petite, being potentially considered loli, they aren't nearly as short as mare. most being just above 4ft. the characters in your games that are that comically short are generally given massive boobs to compensate. in all honesty, short women with big boobs is my preference so i have no issues there. as for the age part, basically all adult games say that characters in the adult acts are 18+, though there are instances where story/character bring that into question. however it is true you don't have any game that does all these things at the same time, and i apoligize for saying otherwise.
