Great game, but a bit too easy
I beat the entire game straight through without losing once, and only a couple times did I feel there was even a chance I could lose. In fact toward the end I was basically invincible and the challenge was gone. I'm no elite gamer so I know that means the experience was probably similarly lacking in challenge for quite a few other people. For that reason I think I'd recommend some way to adjust the difficulty. But maybe instead of just a boring out of place difficulty setting, you could make it more believable by integrating it into the very slick PC-based interface you setup for the game's "plot". Or maybe you could setup optional challenge levels. For example, I think it'd be interesting if the AI allied against you after, say, the first 30 seconds in a level. Or if you could tell a discernable difference between one AI and another, such as one having very high defense but weak attack and the other having strong attack but very slow speed. It felt like all of the enemies I battled were too similar.
I was also looking for a way to go to that competition once I was invited by email at what I think was the end of the game, but I guess that's just your way of transitioning into the next game and I wasn't supposed to be able to attend?
Lastly, I saw absolutely no way to max out all my specs. The best I could do was max out strength, defense, and reproduction and leave speed and agility to suffer... not that I found either one particularly necessary... especially toward the later levels when so many of the cells gave a high speed attribute anyway.
Hopefully you find some of the above helpful in designing the sequel.
