I havn't played marbles since I was weee high. Nifty little game. I think there should be AI's that can fit in to play other player spots.
It's one of the great games too, I love it. But for Chifii said, it needs more fun with a computer opponent.
And moreover, if it's getting good, I hope you develop it for mobile too. iPhone is nice, but the problem has too many problems and yet very expensive, how about an Android instead?
'twould be much more fun with a computer AI to play with - it's a neat time waster, but not much more than that.
Incidentally, this would be a wonderful thing to put on the iPhone or the like. You should consider it, if you have the experience to do so. The graphics and such are wonderful, it just doesn't work as a flash game.
its a fun game, but too bad you cant play against a NPC or something
Shoulda had a computer to play agianst played for 30 seconds then was done.
