Don't expect much in the shareware download. You can't really play but a short bit of it and then it will stop, flash the order screen, if you chose not to buy, it goes back to your desktop. It seems intresting but hard to judge as when ever you seem to just start to enjoy it, wham, bam and back to the desktop. Without at least letting you play a few levels all the way through, I'm turned off by their marketing aproach enough to not buy it, regardless of the game.
