Charmed by the retro presentation, music, and theme! UI work is awe-inspiring, and the minigames with the spam popups and necessity to move the window layered over the core games were the right kind of chaotic.
Only constructive criticism I can think of is I wish there was an endgame with something to note that the viruses were all defeated, and maybe a last stand with that dastardly Beardy admitting defeat (or otherwise getting the upper hand and torturing you ever after in the uncloseable endless mode!).
