So the DEV's Itch.io page is a little confusing.. There seems to be 3 versions of this game.
1 - TP: The Class Next Door [Free Version]:
2gb in size despite claiming to be 1gb on the download link. This version is the F95 version but its up to episode 22 and was updated in December 2022 while the F95 version is episode 8, or 14 episodes behind in content! So tons of new content.
2 - The Class Next Door:EX [Free Version]:
2.7gb in size despite claiming to be 2gb on the download link. This EX version is claimed to be the free roam version of his game (the original F95 one? it already had free roam though right?) It is described as NOT as new game, but a new SEASON with many gameplay changes. I do not know if it follows the same naming/update episode convention but its at Episode 11. Updated December 11 2022.
3 - The Class Next Door:EX2 [DEMO]:
985mb size, kinetic novel version of EX without free roam. Also says it continues the events of the EX version. Idk if that means its just further ahead in development or if EX is now halted and moved to EX2 from now on. New gameplay changes to account for this. Updated March 2023.
I am not sure what to make of this so I guess I will just play them all. Game 1 seems to be the OG F95 release, just with alooooot of updates and new content. Game 2 seems to be the remake of Game 1 he always wanted but its with free roam sandbox stuff that a lot of users didnt like in the Game 1 so I am not sure what he means unless I am missing something or misinterpreting things. Game 3 seems to be the latest and one he is actively working on and the version of EX game 2 but WITOUT the free roam sandbox elements and is purely kinetic, your typical VN format.
Saves from the ancient F95 release wont work. All versions seem to be free to download. You guys might want to look at screen shots and some of the videos he provides to gleam more info and understanding. Dev seems to be focusing on Itchio and has stopped coming to this thread.
