a reproduction of Game and Watch: Ball, in which you play a juggler who's tasked with keeping a number of always hastening circles suspended in the air. We guess the plural nature of your profession's materials would make the title Balls more appropriate, but ... no. No, we won't be doing that.
The game (and Watch) will run you 1,200 coins. Also added to the list of rewards is a reversible carrying bag for whatever model of DS you're currently toting around, which costs 250 coins. We guess you could put other things in there, too. Like Game and Watch: Ball! That, ladies and gentlemen, is called synergy.
