In-game chat maybe?? If you take your eye's off of the screen for a couple of seconds (maybe, per-say to chat with your team mates on the kongregate chat sidebar) the undead will be on you in a second and your down to only half Hp because you cant find your player because the screen has moved from where you have just left it... Thumbs up for the dev's to see!
@ Maganator9 If it was your JOB to make a game, and it gets popular, you might want to get a little revenue for it. Plus, you don't even need the premium content. (unless your a noob)
