I bought the game and like it. The goal is to draw as precise as possible following the pattern (to gain more coverage/score) and also as fast as you can (before ladybird beetles eats up the pattern).

It's fun, but the levels are not that challenging once you know how to play. There are only 10 levels, and only level 10 is more difficult.... I finished the game in less than 30 min. I hope the developer will add more levels in the future. Still it's a good game for $1.

Btw, I experienced some PQ issue when I reached level 9-10. Some graphics turned bad (became interlaced) when the bubbles were popping. The artifacts disappeared once the popping animation stop. But then I'm running @ 750 MHz....
