In our interview with Jordan Mechner (which we will be posting shortly), he indicated that the decision was made to make the iOS version somewhat simpler than the console versions, to facilitate on-the-go, pick-up-and-play gaming for a mobile platform. The main difference is in the attack system. While the console versions of the games give the player both distinct kick and a punch abilities (a button for each), the iOS version uses a single tap for attacks that automatically vary the method of contact.
