Third level... we're not in the Yatterman stages anymore - this is Zenderman territory!

You can actually fall off the cliffs in the early part of the level (even the machines that can supposedly fly will fall into them instead of... you know, flying over them), but there's a bit after the mini-boss where you safely descend to the desert below.

Beating the level is apparently the unlock condition for THREE extra machines... so now we have a full set of 9 vehicles like in the sequel (maybe the 10th one is also here? Hmm).
