I'm making a simple platform game on mobile devices, and I realized the framerate is very low (20 fps on iphone 4), even if the game is simplistic. I'm simply wondering if this is normal.
I know performance on mobile is nightmarish, and I experienced that before on other games. But is it not weird that a mid-range mobile can't handle a simple prototype? I don't even use big sprites. Is it because of the tiled backgrounds?
Here's my proto test: https://dl.dropboxusercontent.com/u/27924504/test/test/index.html
I tested it with an iphone 4.
