I think there's actually a bit of a bug with the Plasma ball. I think that whenever more than one of them happens to hit the bricks, the range is inflicted from each of them, causing multiple applications of splash damage. If not that, then whenever one hits, all of the plasma balls fire off their range.
I really didn't like this. It tries to feel different from the original and level pack, but in a completely wrong way. I feel this may have cemented the idea that all flash games are nowadays are repeated puzzle games and shitty MMO's anymore. So... congrats.
If this is going to be the spiritual successor to draw my thing, well... I'm worried. At least DMT had room for error on guesses, so you could say something along the lines of "dominos" when it's "dominoes" and still get the point.
Just in case there was any doubt, OMGPOP had been bought by Zynga, who soon regretted the idea and CLOSED OMGPOP :*( R.I.P. Draw My Thing and R.I.P. OMGPOP.
Ouch
