A good tornado game that has a lot of potential and works very well with the 'Expanding' theme. it reminds me of Katamari Damacy.
that being said, after consuming the town, there isn't really much else to do, the tornado doesn't seem to get big enough to consume the buildings and there isn't much other places to go. maybe have some different levels and an objective as to how big you should be would improve the game greatly, but in its current state, the game lasts only for less than 3 minutes of enjoyment.
