Insanely addictive... 2122026.8 FEET!
What can I say...
My record is 2122026,8 feet.
Addicting? No shit. :P
To get that far use the newgrounds tank and AK47, fire ONE shot as the turtle comes down from space on him before he hits the ground, you do NOT need to aim directly at him, ONLY in the vertical lane he falls down. He will bounce up into space with the equal amount of force as he came down if he is hit by the rifle. Do not waste one extra bullet per shot, do ONE and ONE shot as he comes down. NEVER LET GO OF W AND D (UP AND FORWARD) or else you will never get that far. And you most certainly will reach further then I have if you release the cannon at the right time and at the right angle (45 deg).
It's all about keeping the momentum of the first shot, never touching the ground. :P
