Monster Musume Dungeons

This is a very old-school game, made in an 8-bit style, and you get to play it as much as you want, simply because it is free. You start in a mansion and you get to meet your own personal familiar. First, you will get to talk to the familiar, who will explain pretty much how everything in this game works. The old-school animations will awaken your nostalgia, and wait until you get to the naughty parts of the game. This is a very simple, and addictive game, with good gameplay and since it is free, you can replay it as many times as you want.
