I played some more this morning and topped out at 1477, gotta use the bank shots well, and a trick I noticed is if you completely eliminate one color of bubbles they stop coming up on the shooter and replenishing cycles. If you clear the whole thing it respawns a new set just like at the beginning except then you get 2pts per bubble popped, but it seems like more bubbles come with each replenishing cycle so it's risky.
