Umichan Maiko VN is not a remake OF UMCH.
"Umichan Maiko Classroom Havoc (UMCH)" and "Umichan Maiko VN" are just two separate games that describe the same period in the lore.
However Umichan Maiko VN is just intended to be a small game that covers only the major story points from UMCH that I felt were necessary to understand references to the UMCH lore in other games.
I made it because a lot of people ask if UMCH works on mobile, and it doesn't for the most part. So I finally just made something small that hits on the necessary story elements from UMCH.
and I obviously wanted to make sure I wasn't spending my time with something that would cause ToS issues.
and that's really it. This game is not trying to be better than the original UMCH and never was even designed to be before I even stared making it. I'd advise anyone that actually can play the OG flash game UMCH to just play that.
And I'd advise anyone who enjoyed UMCH and want to try something similar to try Umichan Sorani Remake (not be confused with the older tyranobuilder version). It functions much more like UMCH did and works on mobile.
