Hello, I've discovered this game last week-end and I have already spent 4 or 5 hours on it. Following the tutorial, I was able to learn quickly the basics. But the learning curve is a little bit harsh. This is mainly due to the fact that the game tries to fit as much as possible to the principles involved in a body, therefore there are a lot of scientific terms and processes to digest. Despite that difficulty, the graphics and music are nice, and I'm looking forward to connect my cell to outside world. I would also say that the ergonomics could be improved a little bit. Nevertheless I recommend. Regards
