3,416,126 in one long combo, but I need to get better at starsliding to get to the Resturant.
Good game, I like the "Ecco the Dolphin" feel this game has.
I think the best way to get going fast is to start by linking a bunch of 'Nice Entry' and 'Schooled' bonus together really quickly, and then move on to the hard stuff. Avoid seraching for rings, but take them if you can. You don't have to roll in the water, so long as you make a fast U-turn right after you enter (don't turn too much or you won't exit the water, and possibly ruin your combo).
