This game takes all the elements of the first game that made it so great, and adds two very important improvements; quicksave and improved gamespeak.
Quicksave means that you don't have to repeat those tough places over and over again just because you made one tiny mistake. So unlike the first one which could get very irritating very quickly, this game is pleasant all the way through, because you can just start over right from where you quicksaved. Quicksave means no frustration.
Improved gamespeak allows for mass control of Mudokons, so you don't have to go back and forth between screens for a group of Mudokons you are trying to save. Additionally you can now control not only Sligs, but Paramites, Scrabs, Glukkons, and even explosive farts (I am not kidding). More variety means more fun.
So if you enjoyed the first one, you will love this one. And if you didn't buy the first one because it was too hard, this is your game.
