Very fun game! I enjoyed the humor and voice lines, as well as the concept. The different mechanics for each animal were quite nice.
There was a glitch in fullscreen where there was gray on the edges--might want to adjust that, or switch the Stretch mode to "Keep".
Very nice idea that there are always multiple boats, as it added a lot more strategy.
I never managed to get a boat's health to 0. It would be cool if the health was lower, so I could actually destroy the boats and stop the rides from getting completed, but oh well.
