Very fun Game, but I find it difficult to survive the 2 type of virus... The Graphics are perfect, cause they are simplistic but coloruful. I'll give the sound effect a 10, but I would wish to have a bg-song for a more unique game experience.
Per total for a 12h game it is more than I could wish for.
I hope u will add some updates to it, more levels and an exit button =))
nice game!
