Nano : The Mission by psychopsam
Up in the domain of the normal human universe, mankind has control, but zap them down to the size of microbes and they become the bottom of the food chain. In a first for DrewFX, the game will be an adaptation of the upcoming ebook Nano. This game will centre around the periless journey the young NanoTeks undertake to test the new found technology that might just save the creator's wife from an incurable cancer. You must take on this responsibility. "On the head of pin, the fight for life has only just begun".

It should be more challenging now that the bug was fixed where you have to slow down to pick up the humans, meaning the worms will have a chance to get you :D
Cool graphics - suits the premise as a nano machine would be made of chunky molecule machines.
