Yeah, mobile ports are generally cheaper, it's sometimes called 'the buttons tax'. I mean, there isn't a person alive who would pay 20 bucks for a mobile game, and in case of OP, even a fraction of that price didn't attract many players - Google Play store says it had only 10,000+ downloads.
There's a number of these games: Bad North, Mini Metro, 80 Days, Crying Suns, Door Kickers, Roto Force, Golf Peaks.

You aren't supposed to pay for these games.
