I finally got this and while I'm only on the third level, I can say without a doubt that A Ride Into The Mountains is an absolute gem of an IOS game that deserves to be played.
The pixel art style is atmospheric and wonderful to look at, and combined with the excellent music, delivers a fantastic artistic experience. The gameplay is just polished and enjoyable as the art. You guide your horse by tilting, fire arrows Angry Birds style; sounds simple, but between the very varied and inventive enemies, and the plethora of projects they fire, A Ride Into The Mountains reveals itself to be a challenging action shooter, as you deftly avoid attacks, shoot projectiles out of the air, and precisely time and aim your shots.
A Ride Into The Mountains is an excellent game, a visual journey that also offers fun exciting action. I can't recommend this game enough.
