Just my opinion but I don't think there is any justification for the $20 price tag. If anything, it gives you a false sense of a well produced script and game. You're extremely limited to what you can do, and often it's 10 days of the same thing over and over. Illogical. Your aim is to have sex, I guess, and you have to say the right things in order to get laid. The right thing is a choice of words of 3 dialogue options every time. That's literally it. There's no background of characters, the lines are obscure and sometimes in broken English. And there are about 10 lines in the whole game, that get repeated over and over and over again. 

Day 1 wake up - have breakfast (no dialogue) - do army rehearsals (no dialogue) - Thomas: Exactly! - You can visit the gym, showers or Thomas' room - You'll usually say "hot ass" and "I should go". Repeat x100. 

All that background information you see on the game page is there because it's definitely not in the game.
