ok maybe,but stefan should look on the app store,he will find numerous games using higher resolution and theyre running just fine.
I think the resolution theyre using is from old gen iDevices from 1ts to 3rd iphones/ipods and that would be understandable since the max resolution on those devices is 480x320.
But he should take look and maybe take advantage of the up to 960x640 res on newer devices and perhaps make an app designed for these and profit $$ along the way  |
Other games probably also code their games from scratch for iPhones and Android devices... Graal is not one of those cases.
