That 4.5 star Google Play rating for the ad-supported isn't one of those generated by just a few ratings. Instead, the app has 20,000+ ratings and still has a 4.5 star average.
However, the big problem, as exposed in Amazon Appstore ratings, is the in-app purchasing required to advance in the game. One reviewer called it a "ca-ching" game, meaning you are charged to buy the game, then "nickel and dimed" for in-app purchases.
As far as why there is no paid version in the Google Play, it's not all that unusual. In these cases, the developer will usually cite restrictions in Google Play, while not elaborating on them.
There is also a version by the same developer in the iOS App Store. That version is also priced at $0.99 and has a 4.5 star rating for the current version and 4.5 stars overall. That version also has a number of in-app purchases, all the way up to $14.99 for 20,000 Gold Coins.

what it means to developers.
Amazon.com opened up the Appstore despite a lawsuit by Apple, which has previously trademarked the term "App Store." Microsoft has filed an appeal against that trademark, saying the term is too generic. Amazon.com has responded to the lawsuit in the same manner.
