My usual reaction to Breakout/Arkanoid style games is "meh." It's one of the easiest types of games to code, and so there are scads of them out there, most of them very dull. I fired up Jardinains with the expectation that I'd be uninstalling it quickly. An hour later, I was still playing, with a toddler on my lap following the game avidly.
What makes Jardinains different can be summed up in one word: gnomes.
