I think it'd be nice to be able to say at what percentages HP you grab what number of enemies. Instead of "always grab 3" or "always grab 2" it'd be "If at 100%, grab 3. If over 50% hp, grab 2. Else, grab 1." I hate getting killed because I was at 45% hp and grabbed too many for me to handle.
I like games that say "Hey you don't want a hard game? Here's an easy little time waster. Oh we're also going to add in this thing for those of you that want an extremely hard challenge." And that they're basically the same game but stuff is things It's awesome.
