Well.. this is not a game.
Its from Unity themselves, to be used for testing and inspiration.
And you can download it for free in their official store.

This is just another scammyscamscam trying to make a few bucks, and they probably injected some info gathering stuff as well.

I wonder what all the people who always complain about games being "Asset flips" have to say about this one! At least this game is being upfront about it~!
