Ok. I'll address your complains...
1)game has too many lines to read... I assume you picked the faster option to get it over with....
2)it's too short... I wonder... if the girls don't like you, you're just given the basic story, no snooping around, no invites for drinks, no sparring offer and not Chris doesn't want a pet... but all of that is on you as all content is optional... considering that the game has multiple paths possible to reach a conclusion, it's a decent content to file size ratio..there's also the option of pissing someone off and that person won't talk to the MC
3) conspiracy theories and the malfunction of the vanguard... Actually both Chris and Annie tell you that something is wrong but since they don't know the MC, an outsider, they must trust you first...
4) Annie must be the gamer because she's Asian ? By that logic she should also be a prude and a master of some martial art.... the first one I wouldn't want for reasons, the latter would be awesome
