The game is free already :), it shows a message asking for support but there's an option just beneath it letting you play.

Well, you actually commented on Five-Days, so in all of my answers I was responding to that, sorry about the confusion. But Midnight Ride has a web version, it should open on your phone without needing to install anything, and if you need support on that just let a comment in the game thread, it will be easier for the team to track the issue :).
