Okay just tried this one, keep in mind Toon stuff like this isn't my thing, but...
3/10 - There are many issues here. Thankfully they are mostly game issues so should be easy to fix. But right now I don't think this is really worth playing.
First, you need to turn on rollback. If you don't have it in the system then ya should look it up, I do like the go back from history, but ya need a rollback as it makes it so much better for the few choices you do have (Talked about next)
Second is the Choices. You have 3 choices... 3. They have only "right" and "wrong" which isn't what choices should be. It isn't a test it is a choice, and should mean something, or well anything. It would of been better without the three choices you put in, as then it would of been just a straight VN. This needs the most work out of everything.
Third I will just call content. Sure there are random conversations with a few good shots made, but you really only do anything with one girl then it ends. To call this Final version means you don't plan on changing anything, but it needs some actual content other then one scene that seems tossed in to make sure it has something in it. I think this was the most disappointing.
Four There was no real... plot. I mean the great thing about most these games are the sex/etc is in context to a story. This is just about it, and it doesn't even happen till the end. I am sorry, but it is just half of the game you might want to look into story writing a bit, and have a story to tell and it won't feel empty.
There are a few other things, but I think I have been harsh enough. I am not saying this is the worst I have played, but it isn't good. Not all games need to be good, but without knowing where you messed up it is difficult to make better. I just mean any bad things as constructive, and as always are just my opinion.
