great fun! great for brain development!

Challenging, fun, 'addictive', but most importantly, combines demands of hand-eye coordination with planning and therefore great for frontal lobe development regardless of one's age. This is the prime example of 'game' that is useful for promoting cerebral plasticity. In other words, eager young minds, this one is both fun and good for you -- and good for the parental units. As the minutes fly by, you will feel the synapses build. Get this one!

Frenzied Fun

The simple game mechanic is easy to learn and hard to master, making for plenty of enjoyment. New levels are challenging to unlock but each area is well designed and interesting to see. The difficulty curve may throw you off, but stick with it and you'll find a game to come back to again and again.

Amazing and free!

The screenshots of this game looked quite unimpressive. However once I downloaded it (which was no skin off my back considering it's free!), to my surprise it was incredibly fun and addicting. I am now motivated to get platinum ratings on all the levels, this game is a casual gem.
