Would be nice for the challenges to have a restart option. Especially for number 4. I'm getting tired of waiting for the shield to die. So far. All the challenges proved fairly easy. The only problem I have is number 4 and I have tried both the shield follow dragon as well as the sword follow shield. I keep having the problem of the shield wandering much too close or that the sword becomes the closer of the two once moving the shield back. Or the shield moving too close while moving the sword back before moving the shield. Either way sword seems to kick the bucket first. The AI does bite pretty badly in those terms. May be easier to have on manual for a couple of seconds after reaching destination rather than it switching back over to the standard AI. Or even having a button to turn it off altogether.
