Hi,
I just found this fun little browser game that's attracted quite a bit of attention recently
It's a simple multiplayer game where you start off as small virus/bacteria/single-celled organism and try to get as big as possible.
If you remember the game Spore, from a few years back, think of the first stage and you sort of have agario.
I won't spoil the fun of learning the game, so that's pretty much it. Watch some YT vids if you like.
But, trust me, it is more fun than it sounds. And damn addictive.
