Serious tutorial problems...
Ok I started the tutorial and was going along fine with the intention of giving this game a ten, when suddenly for no apparent reason eight enemy cells came out of no-where and killed my entire species without me even getting to any section in the tutorial about attacking. I restarted the game and quickly rushed through the the tutorial up to the I was on, thinking I would just have to be quicker to get to the attacking bit. Once again I got attacked before I had even reached anything talking about attacking. I managed to survive with just my cell pool left by placing some penicillin into the game, which killed the final invader. I built a new cell and attempted to continue the tutorial, at which point several more attackers appeared with ranged weapons. At that point, I just stopped playing. So I think there could be improvements, but the main idea of the game was good.
