I love the seaweed physics and behavior; I spent a lot of time climbing through them and bouncing around. Just a heads up, I think there's a typo on the page about the controls (Q, D to rotate, etc.). Nice work!
Oh yeah true, i used an azerty keyboard so Q is the place where A is on qwerty, sometimes i forgot about that my bad, thanks for letting me know. I also like the seaweed a lot, most of the times i'm in there too. Thanks!
