The changes will be :

> Better writing on the endings of each scenario and better dating phases.
> A new lewd route featuring all the main characters.

>Fully translated game.
>All CG and animations uncensored.
> Slight gameplay and graphic changes due the change of engine.

And that's basically it!
The goal of the remake is to make new content for the game easier to make though so after the first version release, we will focus on releasing all the  side characters stories that didn't got release in the original!
