Excelent game
I found a s-m-a-l-l cheat though. If you click and hold on to the pink part of the dumpling, and move slowish, (so the cursor doesn't move off the pink part) the dumpling will be held by the cursor. You can then move around and avoid the viruses better. (this actualy becomes easier to perform as the dumpling gets bigger) It kind of kills the difficulty though. still, I found my self running in to the odd virus every now and then so I guess if you get careless you could still loose.
I liked the music, though, a few different tracks would be nice.
