This is a French game set on a train where you wake up with your memories somewhat befuddled. Then your phone rings.
In general, the game loops and you have multiple tries to fix things. The game also includes some combinatorics, which was nice for me as I was teaching this just a few weeks ago.
Overall it was very short; I only did 2 loops and solved two puzzles in the second loop (it may be worth taking notes). I had a good time.
