Yeah. Built it on my iPad but after an hour, I want to stop... Except he's on another ipad connected to mine.
It's possible using ifunbox, you can get the map file from yours and then transfer it to his, I put my daughter a ton on from the web. I'll pm you some links if you like?
Deus Ex and Perfect Cell are both really cool because you can play then pascifist or offensive. Tentacles: Enter the Dolfin is a great exploration game. Also for exploration and story, look at the game Unmechanical. Awesome puzzles and a cute story. If he likes that he might like other point and click games like Hamlet, Cardboard Castle, Lume, and Machinarium. Unmechanical has more exploring than these other titles though. Oh, and Costume Quest also.
Great call. Air Mail i think is an underated iOS classic, stunning graphics, nice gameplay, always thought that game should have got more love.
I can't believe I forgot air mail. I bought it a while back and didn't really play it much. Maybe the kid will like it.
