Fun mechanic that was well used within the theme however once I left the clouds though the first red rock really got me! I just couldn't get past it. I got there on the 4 minute area and was still there at 10 minutes.
If I was to experiment with mechanics I would of liked to of used the arrows to move along the ground level. And maybe separate the vertical walls and sloped walls so that I could jump from the slide. Just some ideas that popped in my head as I played.
Really fun and would fit into mobile gaming great.
