Wishbone: I made a better icon for the game, if anyone wants it. I've kept the black square around it, but used a higher resolution image. To avoid the stem of the flower disappearing almost completely through scaling, I've scaled the stem to be twice as wide. I think it looks better than the old lo-res icon, anyway.
Now, the forum won't let me attach an .ico file, so here's the PNG. If you go to http://www.convertico.com/, you can convert it yourself easily without having to install anything.

Wishbone: Hmm, the stem was still not too visible, so now I've lightened it in addition to the horizontal scaling.
