Well, it's not like the final version will be 1.0, given that the numbers seem basically random.
As for the rest of the game? There have always been two main parts so to say, one being what happened to MC's dad and the other finding someone for your prom (earning money as third doesn't really count, I'd guess). That second part is what the rest is mainly going to be about, introducing the remaining school girls, the dating system and the prom itself. Next to that there are certainly quite a few other, smaller stories like the teachers includnig Coach Bridget, Erik, the library, etc. left.
