I really enjoy all the improvements from the first installment of the game. The added interactivity gives the new version a more involved feel than its predecessor. As an avid flash gamer I appreciate quality and this game has so much potential; however as others have stated the lag is a severe detriment to the experience.
So happy that Infectonator had a sequel! Thanks a lot for a good game! I really enjoyed the new advances in upgrades and increased difficulty in general.
