Not surprising, good indie games sell on all (popular) platforms, especially if they are published by Devolver (they have a solid indie fanbase).
It sold 200,000 in its first week last year: https://www.polygon.com/2016/4/12/11414404/enter-the-gungeon-first-week-sales
So far it almost sold 1 million units on Steam: http://steamspy.com/app/311690
