@mercuryus: How can you compare the collecting of fishes in swarm with your cruel(!) fishing game!

Thank you all for your kind feedback!
I got the idea for the game in Februar of last year, when I heard about a company with a swarm as logo and their 'credo' "together we are strong". I developed a small demo. Later, i've seen that the idea is quite common, there are several companies and organisations with a swarm of fishes as logo. My sister showed me a book for kids from 1963 called "Swimmy".
In December ChrisB joined the team, the game got its own characters, I developed a furry skin by accident, and thought, hey, this fits with the unreal world where a big predatory fish is sooo slowly that such a small fish can survive.
Why "Fish On Wheels"? There is a "swarm speed item" in the game beside others, and when using it, it looks a bit like on wheels. I think it makes curious, and when seeing the game after following the name's link, people won't be disappointed, although there are no wheels in the game!

I don't plan any different swarm AI, because I felt the movement is complete as it is now. It works only without collision detection.
The framerate was bad when I made the video, around 10 fps on my 3GHz, 1024RAM, Radeon X300, but I exaggerated the number of fishes, and I'm still optimizing.
