Well, what a fresh new game developed by Matthew Wegner and his crew at FalshBangStudios. The game relies on the Unity Webplayer, which you will have to download first (about 3MB) to play the game. Unity is a kind of Flash, but only dedicated to game development.
The game is a kind of Puzzle Bobble, improved with a powerful physics engine.
You can view a video demo on Matthew's blog. Morever, the game is provided with a level editor to design and share your own levels!
