I'm definitely a fan of Connect Four, but this presentation leaves much to be desired. For starters, the controls are just god-awful. Either select the column in which to drop your piece, or have the piece follow the mouse instead of swinging about underneath it like a sentient but retarded pendulum that guest-starred on an episode of Family Guy.
Second, the AI seems... well, simultaneously difficult yet stupid. Several times it's managed to corner me in a position where no matter what move I make, it can win, but then it proceeds to ignore its own setup, allowing me to block all of its available victories. That needs work.
Visually, not really anything special, but it's not bad on the eyes. It's really just the control scheme that irritates me enough to take 2 stars away.
