Two more new DS games from Level-5?
Akira Tago's Brain Exercise Vol. 1: Travel Around the World Solving Puzzles and Sloane and McHale's Mysterious Story were both listed in the same issue of Famitsu in which the other games were announced, though these two were buried in the schedule for 2009. We don't know much about Sloane and McHale, but Akira Tago is the puzzle master whose works inspired Professor Layton. That's all we need to know!
