Interesting theme. indeed very apt as a light game! Can i assume that it is a 2-4 players game since i read that they are 4 tokens? I like the cath-up mechanism that as the boat gets heavier less movement points. So each player must exhaust their movement points at one go. Maybe designer can consider what happen if each player uses 1 action point before moving to next player. will that allow better player interaction and less down time?
I like the alternative dice mechanism provided, but it lacks the catchup mechanism.
