Wow... some of these levels felt impossible (14 and 19, especially), even with the walkthrough, until something clicked and I understood how to do it. A big help was that you could cut multiple tentacles at once, making it easier to make large attacks against a cell.
Great graphics, good music, and great concept, but all the quirks, bugs, and glitches made the game more difficult and frustrating than it should have been. This would have been an awesome game if it was given a little more polish on the gameplay (maybe in a sequel?); as it is, the gameplay really brought it down. 3/5
