Haven't covered anything from the indie scene in a while, so here's a quick pointer to Blush, a 3D browser game from Flashbang studios. You're a carnivorous sea creature, using your tentacles to smash squid, crabs and other sub-aqua baddies in order to collect their eggs. The more eggs you get, the more powerful your attacks become.
The control interface is interesting - you use the mouse to spin your tentacles in an aggressive style - and the graphics are gorgeous. There are obvious comparisons with flOw, though the four-minute time limit brings in a tension that is absent from the PS3 cult classic.
You'll need to download the Unity 3D engine to play, but it's worth it for the visual style alone.
