And a zombie version.

This game is really quite fun, and rather addicting. I like drawing new shapes out of the falling sand, or pouring water on the plants to make them grow...then set them on fire. :D
Yey, I knew about abou the sand one, but zombie = 10/10
Thank you for wasting 1.5 hours of my life.
It's great to set up a nice growing plant... Water it and see it flourish...

And then, BOOM! Light it on fire... Preferably with some oil deposits strategically placed to cause some "explosions" along the way...

Good stuff...
If you want to see something creepy, set up an elaborate waterworks fountain. At the base, add one plant dot. Then turn on the water.

The plant grows and actually climbs the stream of water until it PLUGS it. Quite scary. :o
Dang, that IS addictive. I keep trying to set up a self-sufficient fire that doesn't involve getting the oil spout torched. It's probably not possible to create a truly indefinite-length fire without lighting the oil source on fire, but it's fun trying to see how close you can get.
thanks sarmy. i've now spent 2 hours at work without doing anything productive at all :(

hahah this rocks.
