Here's a few sprites for a game I really want to make. I've made a lot of different sprites and I've written a bunch of concepts and ideas down. All I need are coders now, as I dont know how to do that myself.
The idea is inspired by the Cell stage of Spore. The idea is that you start as a small alien organism, and you evolve. You do this by eating Algae (Herbivore), Other Cells (Carnivore)
or both (Omnivore).
I've also got a mockup of how it could look here: http://i.imgur.com/amF2LTI.png
You can then get bigger and stronger. And that is kind of the idea put very simply.
