I have an untold amount of turtles stuck between the rood and the saws. There should be a safeguard against that, such as the saws not being fully solid, or more space between the saws and the roof. As a result, in the last 5 or so minutes minutes, I've got a 2'000'000 combo and counting.
what i did to beat bonus level 3 is wait about 9 seconds ( from 1 as soon as i hit restart) and made a line to split it down the middle, slightly to the right side, that way you lose two of the snake things
