Although the MC of that game is not exactly a cutesy twinkThe game 's name Everything Changes' but its currently on pause because the developer is unwell
In general, though, cutesy twinks are the to-go for main characters. The almost totality of Japanese boys' love games have that for example. Among the western ones, Bound to college, Coming out on top, Once more from the top, Bound by night, Ergi, YAGS are the ones that pop up into my mind at the moment.
