I really like this game, but for some reason, I cannot use the other guns in the game outside of the pistol. I will purchase them, but I cannot switch over to them once purchased and when I try, my pistol will disappear. I can't seem to use any of the drugs either. I feel like I am missing a large chunk of the game because of this.
Lastly, there are characters in the game called "minor goblins", which implies a shota element . For me personally, I don't want to play games with this type of theme because it grosses me out a bit. Most erotic/hentai games typically have tags to indicate this type of element (or at least they mention it somewhere) but I did not see any clear indication of this in the description.
