Jools Watsham has confirmed via his Twitter account that all 60 Mutant Mudds levels have been tested and completed and should be available in roughly five to six weeks. The additional levels will be available as a free download pack from the Nintendo 3DS eShop
All 60 Mutant Mudds levels tested/completed. Looks like this game is nearly ready for eShop prime-time!
Nearly = 4 to 6 weeks btw. Mudds needs to go through Nintendo testing and then get in the queue for update/release.
