This dev puts out truck games, this slash one, and now also a fighter one. A jewel one too.
There's more that I can't think of.
Usually the games are made well.
He constantly remakes the games, resubmits them to apple so he'll have more promo codes. He fills the app with ads so he can make the money off of it. They are always paid apps. When the ad is conveniently placed, and people accidentally hit the ad, he makes more off of people that have good intentions of helping him .
