Nice upgrade
This is a very smart game. I really like the music, it makes the game very epic. The game is very well done and must have taken a long time to figure out what does what and at what rate. I like many of the new additions but I really like the old one. You need to find a middle ground. Bring back the virus characteristics, and you got a really good game. It isn't hard just very hard to understand at first. Maybe make a tutorial vs. the numbered help sheet.
Either way it is very good. Well done!
