Dear un-Muters,
You can now choose to start a new game (thus overwriting progress data if any) or continue a previously saved game whenever you launch "Mutated Muter's Invasion" and get to the 'START' screen. Your progress is now saved whenever you complete a level. What's more, even if you choose 'NEW GAME', you will not lose previously saved progress (if any) until you complete the first level, so you always get some time to change your mind! Choosing 'CONTINUE' lets you resume from the level that follows the last completed level, with all your collected items intact.
