Professor Layton and the Miracle Mask is a puzzle platforming game developed by the independent Level-5 studio in Japan. You are asked to go to the Carnival City of Monte d'Or to discover the mystery behind the masked man. In the trailer it is said that whoever wears the mask gets all this great power so the man raises many suspicions. There will be a ton of puzzles to keep you occupied, you will need to talk to a lot of people in the game to discover the whole mystery behind the mask.
I went on the Nintendo eShop and could not find a demo to try out the game, so don't have an opinion on the actual game at this point. I would love to try it out though. You do get little previews of what to expect in terms of the puzzles on the site, I would want to see more though. If you do find a demo of the game, leave a comment down below just so others can know.
Have you played the previous versions of the game? How about the iOS game Layton Brothers:Mystery Room? Of course it has only been released in Japan so far though. Post on the game releases will come a lot sooner, most likely will become the first post of the day.
