I don't think we need different color baddies. What we need are new baddies. The bats were pretty cool and all, but it would be nice to see some newer baddies. I know they have a lot of different kinds of baddies they just don't use them. Maybe they should add/change baddies around the map so people will have fun killing new enemies. Personally I think they should make a mini dungeon and each room as you advance gets harder with more difficult baddies. Once you defeat all the baddies in each room the door opens and you move on to the next. In the final room they could have a treasure chest with a prize in it. Then you can do it again just for fun.
