I just love this game, everything works so perfectly. My only turn off might be the balance of the game, loosing a combo against that naughty virus enemy made me instantly every time.
Yeah, the game is unfortunately not finished so this was part of things I didn't have the time to work on. It has some balance potential but I literally didn't change the base numbers I've used to test the game... It has somewhat of a complexity that makes it tricky but if I had more time (and more test time) i'd be easily able to tweak the numbers. :) as you progress in levels, the game gets too easy (cause i didn't add tougher monsters)
