RiverCrossingDS by MangledLftThumb sees an update. Aim of the game is to cross a river which might turn out tricky.

March 23, 2007] – v0.31

Fixed sound problem that prevented adding any more puzzles (moved the sound over to channel 1 – now all is good).

Added a couple more puzzles.

Made it more friendly for our left-handed friends (i.e. allow R button to change log orientation)
