Organisms it's the classic "food-chain" gametype where you have to combine quick sighting and fast reflexes in order to avoid bigger organisms and absorb smaller ones.
Your organism remains always at the center. You may make it flow by tilting your smartphone onto the desired direction.
Additionally, there are 5 effect bubbles which results in different effects when absorbed:

- Double points
- Triple points
- Hyper sensibility (organisms move faster)
- Optic failure (reduced visibility)
- Reverse genetics (absorb bigger organisms, get harmed by smaller ones)

Organisms game was built to support an article for portuguese PROGRAMAR magazine.
