The blob game? Holy ****. There was a poster on the Wii boards on IGN who posted a link to a blob game he was making. Like 8 months ago. Maybe more. He wanted to make it into a Wii game.
It was a PC demo. He said he wanted us to try it out, and give him our thoughts. Played it some. It was fun, but you couldn't do much (it was obviously a very early demo).
I'll see if I can find the post. I doubt it though. It was quite a while ago.
Anyway, it looks just like this blob game, but with the graphics a little more outdated. What you do, is roll around and run into the buildings. The buildings then turn into a color. The color depends on what color your blob is.
You can change your blob color by running over something. I forgot what. There are black enemies that turn you into a black blob. That will erase the color from the buildings, turning it black I think.
Now if I can find it....
Edit - Now that I look into things further, it seems like the PC game from 8(?) months ago inspired the new game.
