When Pocket Legends first came out, my iPhone 3g played it decently. It gets shaky frame rates but that's to be expected on the older hardware. It was acceptable up until the mini dungeons were added. These dungeons are, for the most part, unplayable. The game will occasionally freeze up for 10-20 seconds or just play at such a slide-show fps that I can't really do anything. Most of the earlier levels play fine (laggier with more people obviously) but this seems to have gotten out of hand.

Is there any way you can tweak the memory usage for the older hardware? I have both anti aliasing and high quality turned off which helps some, but not enough to make the game playable. I have also disabled all the lag causing iPhone features such as notifications, location services, and mail fetching. I am apprehensive about purchasing the newest level pack because if it's as unplayable as these other new levels, it would be a waste of money to me.

Please advise.
