simplistic
This game is way too simple. Unlike brains, its actually tolerable. It's reasonably fun the first time you play it, but I can see it getting old fast. Try and add more depth to the game to make it more enjoyable.
P.S. This is a bit off topic, but I think you should take something out of negative reviews to improve your work. Maybe its just me, but it seems like you're just shooing away a lot of the negative criticism. If I'm wrong and you are taking advantage of negative reviews, then you can just ignore this portion. This is just my take on your responses.
