The developers say it is a little bit of Katamari Damacy and a little bit of Gish. Before Penny Arcade Expo I didn't know know Tales From Space: About A Blob existed, let alone what such a combo makes.

This single or co-op game launches in January as a downloadable game for the PlayStation 3. It's a side-scroller. One or two players control blobs that need to absorb enough candy, junk or, eventually, people and buildings, in order to reach a threshold size and then continue further into the game. You get bigger, level after level.

The concept is simple. The graphics are clear, cartoony and pleasing. The controls are basic, just complex enough to allow movement, jumping and any ejection of the junk you've absorbed.

This game will excel if it has good enough level design. As you can see from the video, the build being shown at Penny Arcade Expo showed promise in that regard.
