Fungi / is a strategic online multiplayer game in which you battle the rest of the world. Grow from a single cell into a multicellular fungus by leeching mass from other players. You move around by placing new links and transfer energy from cell to cell. Fend off attacks and try to conquer the map whilst keeping your network intact. There are multiple ways to defend, attack or avoid others and there are a couple of powerups to help out. With the right strategy even smaller fungi can be a threat, so watch out! Try to make it into the top 100 and immortalize your name in the hall of fame or challenge friends in a game of Fungi.

Very cool mechanics, but there was a bug for me when right clicking i couldn't get out of scrolling the screen any more.

Thanks Rottjung!

That is a known (unresolved) bug, were you able to get out of it by fiddling with the mouse buttons? We'll look into it a bit more and hopefully fix this soon.
