I think there is a glitch.... ### 2/5 — Needs to be fixed *2016-10-09, version 1.02* The game has only one scenario and the help text is trimmed at the end. It needs to be fixed. I recommend "The River Tests" by SolverLabs ### 5/5 — Great game *2016-06-13, version 1.02* It’s a very fun game to play.
