This is a pretty fun rts/rpg lite hybrid
. The controls are really basic and as simple as it is you really do have to pay attention when things get hairy. In short, you select a party of up to four classes (rogue, knight, wizard, witch, barbarian, bard, and cleric with some possibilities for doubling up classes) and fight critters by dragging a line from the character to the thing you want to fight. (Or the thing you want to buff) It's $2.99 iirc and worth it on the iPad, although I could see the iPhone being way too tiny.
