Particle is a puzzle game controlled only with the mouse which attempts to 'stimulates your eyes, your ears and your mind at the same time'. It looks and sounds very much like recent ambience puzzler Osmos, but gameplay-wise it's actually nothing like it.

No, what Particle actually is is quite difficult to explain. The key is to work out where your glowing particle needs to be moved on each level, an each solution appears to be quite different. What it does have in common with Osmos is the selected soundtrack with track names such as "Oceanic", "Parallax", "Shanana" and "Solitary".

The flowfase site doesn't give any details on when the full game will be available and this demo is extremely short (about 5 minutes worth of gameplay) but it's worth checking out just for the odd calmness of it all.
