If you install the propellor early, then the whirlwind, you get bonus points. The aerial seems to get you a bonus when it's finished, too. The egg and the ladder don't seem to do much. Apart from that I have no clue, though it seems good if you get into the air as quickly as possible.
oh, and the cyclone powers the planet by turning the propellor. that makes the thingmy at the bottom spin, and the screen turn on. the key is in when you let the bubbles go.
It was the lush paradise...you have to let the bubbles form the rain cloud. If your propeller's gone beyond Level 1, then they'll get blown away and you end up with the lava flow.
What a brilliant game! Just finished it now after a few hours of fiendish rearranging.
SPOILERS and hints -
Yes, the mountain needs to be a lush paradise, which means that the sun tower needs to be built early on to be large enough to cast sun on it, and the pipe with the bubbles has to be installed before the turbine, or else the turbine blows the bubbles away.
The twister needs to put in after the turbine, or else an advanced twister will destroy a tiny turbine.
The cog tower is powered by electricity made from the twister-turbine combo, as is the screen.
oh, dude, wait until he maxes out too!
its my favourite one.
well, apart form the planet shaking flashing blue light bit.
and the sustainable electricity sourcing.
