Oh, so this is the origin of the cute chibi girl from Bathroom Offroad! She's even more adorable in this game, really.
The sexiness played in a more comedic than purely pornographic direction is quite fun, and the over-the-top curvaceous chibi proportions of the character definitely help sell it.
The boss fight was quite fun, and the game overall is quite hilarious, especially any stage where she's doing something weird in the background.
My one complaint is that mouse controls are kind of awkward, but then again, this was clearly designed with phones in mind.
