Pretty good.
I thought it was okay. It certainly had a distinctive graphics style that worked well. I don't really like the idea of blowing up "noobs", but whatever...The game mechanic was simple, but interesting enough. I played until I got to bouncing Os, which made it more difficult, so I could tell the game wasn't simplistic. Which is good.
My one big issue was that it took so long to play. The first few levels were pretty much boring because you only had to move once or twice, and yet they each took like 30 seconds of waiting to get through. Oh well.
