Ex Vitro development is kind of on hold, as I've been putting most of my efforts towards a new game called Syndemic.
It's a microbiology-themed action shooter with elements of item collection and puzzle-solving built into it. I'm trying to create a blend of Diablo/Torchlight type of adventuring plus shoot-em-up style gameplay.
I'm hoping to include some semi-educational elements in it, such as exploring microbiology ecology and human diseases. It's quite a bit different than Ex Vitro, but I hope you give it a try.
I've also got an experimental funding site going on Indiegogo.com. I'm not sure if I'll make much from it, but have a look if you're interested. You can name a species of microbe, design a weapon, or have your eyeball turned into a battleground.
