Hm Well I don't seem have any trouble with the controls or doing more than one thing at a time since I'm used to playing video games. Using the arrow keys and the wasd keys isn't at all confusing but I just haven't got used to the fourth screen yet I feel like I could do the first three all day.
Fun not so hard you just have to replay a few levels for upgrades sometimes then it's really easy once you get slighty ahead in upgrades. Boss was very easy if you got a fully upgrade laser and full speed upgrades.
I don't see what everyone is talking about I enjoyed this game. I liked the twist of being the goverment instead of the virus but more options are always nice, still it's a good game and just as enjoyable as the other Pandemic games with the same flaws aswell.
You don't have to kill them and sometimes if you do the hero gets a bad rep. Like when I got a hero to kill my watcher water dragon. It said some dragons find themself bitten by the bitter blade of greed that plague the very humans they sought out to protect.
