Great game with 2 flaws – DUAL – a game about computation Review

I've been wanting a game like this for a long time. The gameplay and game design are lovely. However, I have two complaints: 1) I cannot rotate my iPad upside down to play the game. This means the charging cable is awkwardly jammed into the table or my lap as I play. Makes playing the game significantly less enjoyable. 2) I'm a geeky nerd and I find the instructions confusing. There's no way I could show this game to anyone except programmers and have them understand how to play. I could use a better explanation about what each selector option does.
