I had fun streaming this, but also kinda laughed at the meta of it being a DS game and the device the main character uses is clearly a DS.

An experiment has gone wrong and the main character's father has disappeared and you need to solve puzzles to get out tough situations and solve the overarching mystery going on.

Beyond this I don't remember much beyond frustration that one of the solutions to the puzzle was to close the DS. Something not too obvious when playing with an emulator.
