This may not be what you have all been waiting for. Or it may. This depends on your expectations.
It is, however, what I have been waiting for: our first official release.
Thrive 0.2.1 is in-engine and working beautifully, for what little content it has. Currently, your options are limited to swimming and collecting compounds- there are other AI cells to compete with and bump into, and pushing the poor blind hexagonal concretions is wonderfully diverting, but there is little in the way of gameplay.
The great accomplishment of this release is our engine, which is handling beautifully and poised to accept whatever we throw at it in future releases. Atop this, our compound management system performs exactly as it should, keeping your cell's metabolism in check by metabolizing, excreting, and absorbing compounds from and into your environment.
This somewhat tedious release may seem anticlimactic, but further additions will prove that this demo has a lot more to it than meets the eye.
For now, enjoy 0.2.1 while it's the pinnacle of our accomplishments. Its status as such will not last long.
