I'm playing dungeon hunter 3 on my iPhone and its really cool because as you level up the mobs movement speed increases.
birds are the craziest. you can run, but they stick to you like glue. lol
the stagnant 80% movement speed that we currently have for mobs is a little off putting for me.
it's super hard to die. if I get lower then 20% health I run. mob gets one more hit at best.
