Algodoo

Done. Again. By me, again. This time it`s much easier and faster and the new vehicle has more features. I only used slightly creative packaging to make it fit, and even with the tail extended it fits inside the outer perimeter of the starting area this time.
Arrow keys to move, DOWN to brake, UP for a somewhat erratic jump. Jumping can also unstick you from almost anything.
A and D control the tail if necessary, S will brake.
Right shift to arm the cannon for the first drawbridge. Enter fires it and backspace drops it once you`re done with it. It`s best to fire it while sitting in neutral near the end of the spinning wheels.
Backslash (\) releases the kamikaze speeder for the second drawbridge. Give it some room to accelerate because if it hits the block o`doom too close to your side the bridge disappears or goes crazy. You can jump the gap if that happens, though.
