Really nice mood and visual. The nano-ship controls are very intuitive to use. I couldn't find the viruses, although I could see some blue shots (?).
The controls are a little hard to use, but the experience was pretty neat. I'd recommend transferring steering controls from the mouse to the keys.
Great atmosphere for this game! I really enjoyed playing it! the controls were interesting and took a little while to master! but in the end I killed the virus !
Feedback on the progress, like a simple counter of remaining viruses, would have been nice.
