First off, I must say this is a good start. However, friction appears to be non-existent, there's no pause menu and no level select option when you beat a level, and you are required to get a high level of points right from the beginning to unlock the next set of levels. On the other hand, the concept is a good concept, but I also think that it needs tweaking.
I think Dave is real because at the hand-writing analysis part, his is one of the papers you have to exclude, suggesting he actually not only exists, but also attends classes (contrary to what he told you at the beginning of the game)
it's pretty good. i love all of the units, and the super soldier is practically invincible. i just love all of the turrets. it definitely serves it's purpose.
i love this game sooo much!!! i think the first one sucked but this one's much better. i like all of the symptoms, but i can NEVER seem to infect the entire world...
