The folks at Mobigloo have just released their latest game for BlackBerry, Balloon Filler. Balloon Fillers works both on the BlackBerry Storm and trackball/trackpad device models and sells for $2.99.
You'll want to watch the video above to see Balloon Filler in action, but the concept is pretty straight forward. The goal is to fill the screen up with balloons while avoiding the bouncing balls. You only have so many lives and balloons per level, so you have to think quick and act fast if you want to keep progressing. No free trial on this one, but it's definitely a lot of fun for just a few bucks.
