Allright
Ulluhtac, when you explode is determined by the amount of proteins you eat. So when you let him run around eating all the protein, he'll live forever.
This game is ok, but in later levels when its just you and a bunch of Virus-Immune guys, it's annoying, because even when you're big enough to eat them, they just run into a cloud of viruses, and then you have to risk infection to eat them. I figured that was the point, but I thought it was kind of cheap.
I loved the spike upgrade thingy. That was good fun.
I think this game would be better if you could spend points or something to upgrade yourself. Like "start with more allies" upgrade, or "faster movement speed" or even "immune to viruses"
You could even make multiple viruses with different effects. This one makes you shrink (like the one in this game), this one makes you move slower, this one makes it impossible for you to win if all of your copies are infected with it, and so on.
Good job. Keep it up.
