I just played this tonight for an hour and 15 minutes and would have played more but have to get to other things.
Amazing game! An on the rails shooter with adult themes. Yes like the people that like their anime I have to admit I liked the strippers and more I saw in this game even if they are not real. LOL! The game is comical having some really well done cut scenes. It has stat tracking, items to collect/goals and different levels of difficulty so it has replay value. I got this for $5 or so in a Steam sale I think. At it's current price of $13.99 I would still recommend it.
