Alto's Adventure has excellent graphics (pictures)
This endless runner has you speeding down a mountain, but what you see on the way is as much of the experience as the gameplay.

Alto's Adventure
Alto's Adventure is not a new gaming concept or the best in its genre, but the graphics as you speed down the mountain are in a league of their own.

Scoreboard
At the end of your run, you'll get a rundown of the distance you traveled and several other stats.

When a mountain elder is in hot pursuit, he will not rest until he takes you out. Your only escape is to jump over a chasm he can't cross.
I didn't make it.
Nighttime on the mountain
There's not too much to this shot, but it's so cool-looking I had to include it.
