Flipper Critters review at IGN.

"In the three years of the Nintendo DS system's lifespan, there have only been a handful of pinball games released for the portable. A small handful, actually: Metroid Prime Pinball is still king of a very tiny mountain. Flipper Critters enters a barely tapped market and tries new things for the genre, and while the core pinball's solid with impressive visuals on a technical level, the surrounding presentation's a little messy and cluttered. Still, the price is definitely right as it's one of the first Nintendo DS games to debut with a price that cracks the 15 dollar barrier."
