It's incredible to believe that we can hold such tremendously powerful devices, such as the iPad 2 and iPhone 4S, in our hands, Chair Entertainment founder and creative director Donald Mustard has told Edge magazine.

Speaking about the visual advances made between Infinity Blade and its sequel, Mustard said: "We'd never made a game on iOS devices before Infinity Blade, so a good amount of development time was spent figuring out the system, what we could do, and how to make it all work. When it came to making Infinity Blade, we were able to make much better predictions about what the devices could handle, and develop some tricks and processes that really allowed us to push the graphical fidelity of the second game.

"That being said, we also looked at where the hardware was headed and were able to increase some of the rendering techniques that were used in the first game, such as dynamic shadows on the characters, and dynamic light rays filtering through everything.

"Even having made the game, I wake up everyday and look at it and I'm like, 'I can't believe that hardware we can hold in our hands is this powerful'. It's incredible."

The ever improving hardware found inside Apple's devices does, however, pose a threat to offering continued support to the older, less capable hardware.

"It will be interesting to see, if [hardware] continues to accelerate at this rate, how long we can continue to support [older devices]," concluded Mustard.

Chair currently supports as far back as the 3GS with Infinity Blade and its sequel.
