Very cool little entry! I thought having an AI to play against made it really interesting! It would be awesome if matching 4 or 5 marbles would cause a negative effect on the opponent somehow. The only downside to this game is that throughout my different playthroughs there were a few times when I was just stuck (no ability to get a 3-match) fairly early on, and I had to sit for a good min or more to lose. Awesome job on the execution!
