10 gates and 5 big plastic ducks... Paddle down the river, going through rock-gates in direction indicated. Bonus points for picking up the ducks. ARROW KEYS: Left/Right - go left/right. Left & Right at same time: go straight. Spacebar + arrow keys: paddle/turn backwards.
Attempt to make game out of formula for flow round cylinder. Thanks to either @Raucket or @Layzej (can't remember which) for the atan2 function. Sounds from Soundbible.com.
