Mr. Chubigans, who created Ac!dbomb/Shellblast, Sandbox of God, Vivid Conceptions, Ore no Ryomi, and other classic Game Maker games, has released a Match-3 style game, Spirits of Metropolis. I played through the demo and it kept my attention longer than most games in that genre do. Even if you hate casual games it might be worth checking out, as the gameplay was a bit more varied and challenging to me than most games in that genre.
