Ducks! The first nanogame, and it's a target shooting game.

furys crossing the river by g (gingermuffins, I think). The only nanogame submitted so far that isn't by me, where you have to run faster than a homing bullet.

Big Red Button. Need I say more? I just thought this would be kinda fun.

And the new one, One-Ball Juggling. Inspired by those old games whose graphics use the same technology as a digital watch display, in this game you control a stick man with no arms and try to keep that ball in the air.

Oh, and I stuck Eight-Legged Express from the Small Games Exhibition in there because Jotz still hasn't posted a followup thread.
Enjoy the tiny games, everybody!
