I'll give my honest full rounded opinion on this.
Graphics: +3
Controls: -1.5
Originality: -0.5
It rounds up to one star. Sorry, but it just isn't... my style.

Fun

Didn't I see something very similar to this on the Game Maker website a couple years ago? Is this a port?

Hm...

The game's concept was kinda unoriginal some other artist used it already...
Easy to learn controls
Tornadoes are FUN when used to destroy and cause HAVOC !

not bad for what it is

good mindless fun.
unlike the previous reviewer I liked the control style, had no problem with collision detection, always got power ups easily.
and just mindlessly tapping the spacebar and watching the buildings deflate.
I like the building animations and the destruction path.
would like it more if debri randomly flew a;; over the place and landed on the ground. and also the destruction path doesnt need to fade away if you use a bitmap data object.

Boring.

The artwork was great, but it bored me, after the first round I stopped because it did not keep my attention.
