Monster Musume Dungeon
The art of this game will bring you back to the good old days, when gaming did not necessary mean that the game has to have good graphics. With that said, this is a game with rather interesting 8bit graphics and great design. The animations are slick and a bit old-school. I think that you will love this game, especially since you are able to play it for free. Everything is explained by your familiar, who is a little fairy you get to meet at the beginning. This is a point and click game, so enjoy exploring.
