So awesome concept, and definitely DEFINITELY got out of control. My biggest complaint was the backspacing. Sometimes it would take forever and the multiple keypresses so frantically felt very abusive to my keyboard (I know that's on me but it's also part of the emotional state you are striving for). Some form of system change there, either allowing a single keypress that speeds up or a clear row option. Also I think linking virus generation to typing speed will help account for various skill sets. Then implementation of the viruses felt perfect, including the timing and number of strokes to kill. Awesome work :D
