It would be neat if they allowed multi-touch to let you place several blobs at the same time, it would make it easier than the desktop version and would warrant specialised levels to take advantage of it.
The point where I realized that they knew what they were doing with the iPad design (and not just simply porting) was when I realized I could pick up a blob with one finger and scroll the world with another. In other incarnations of the game, you have to drag the blob to an edge of the screen to scroll in that direction.
Is this just a direct port or are there special levels for the iPad, I already have a version or two of this and if it has extra content I might be worth a buy but if not... I think I'll leave it
There are a lot of apps that are much cooler on the iPad, especially the generative art and particle physics ones. For example Art of Glow, Little Uzu, etc.
