Corey, I just verified Adam's Level 1-1 score.
Nice job, Adam. A 300 point re-jump of that 2 barrel combo prior to the top hammer grab, a 500 point smash of the fireball that got away, and 200 points for the pair of "bagels" (2 barrel jumps that yielded 0 points), and you could have gone over 11k. Then again, a gameplay alteration of even 1 pixel changes how everything else plays out.
One suggestion: on the rivet screen, if you want to kill off your remaining lives quickly, just run left, climb the 2 ladders, and walk off the edge of the platform.
