A Perfect Fit for Your DSi
That's about it. There's a second mode you can unlock by beating the high score that's essentially the same game, only you're spitting to destroy the seeds. The whole point is just to see how high of a score you can get. There's no extra features, but for $2 bones, there's not a lot of room to complain. It's the perfect game to have built into the DSi because it's always ready to be played wherever you are.
I'll say it again, this is what a DSi game should be. If you still haven't dropped your free 1000 points for signing online, I would recommend this game to compliment something like Brain Age Express: Math or Aquia (where you'll still have some change leftover).
