If you didn't pay the games creator(see the description in the OP) then you haven't played the 2.0 version. 1.0 is alright, but aside from dialog it is basically impossible to distinguish between the girls, at least from your vantage point... But all the really nice CGs showcased are from 2.0.
Games from China? Similar to that, there is the super soft rice master, who becomes the toilet in the women's restroom and the daily life of the NPC tool.(超级软饭大师,成为女厕的马桶,NPC工具人的日常,)
