Hello, Currently, I'm working on an iPad game. I would like to ask you what is the resolution requirement for an iPad game? Should I use (2048x1536) or (1024x768)? Will Apple reject my game app if I choose 1024x768? I also would like to make my game compatible with iPhone. Should I make 2 separate apps (iPad and iPhone) or an universal app? Thank you so much for your help.
