Help the blob ecosystem stay alive. Once upon a time, there was a blob ecosystem on your screen. Blobs have to eat other blobs to create more blobs. If the time is right blobs of the same color can breed. Each time a blob is created you get a point. If a color disappeared from the ecosystem the game is over. If a blob colony grows too large, it may catch a disease, and the population will collapse. Use the tools to help control the blobs ( if you can). You start off with just your finger, and then you’ll get some basic geometric shapes. As the game progresses you’ll get more tools: bioweapons to spread disease, nuclear bombs, radiation to mutate blob behavior. Get wind to blow the blobs. gravity and antigravity to push the blobs, and black holes to suck the blobs away. The most powerful tool of all is love.
Good luck and enjoy.
