I played this with the initial engine, surprised it's not finished after this many years, how is the experience from the original? Better? More content? An easier grind? Was fun and interesting initially since there were not many games like it.
I've noticed that developers these days don't want to finish their games. They would have to start making new games so that people would continue to pay them. They'd rather rework the whole game at some stage, add some new scenes, just to make people pay them the money they're used to. It's the same with this game, which the developer has been making since 2017. It doesn't violate Patreon's terms, so why not…
In this case, the problem is also that the developer creates another game that he updates regularly.
As for the content difference from the old version, the game is different.
More people and students were added, some were removed. The personalities of some of the students have been reworked and overall there are a lot more girls to fuck.
