My mouse cursor got stuck and wouldn't go below a certain points so I paused it, and while it was paused I saw a para shooter walking and went off screen. It made me lose some life and it played the sounds when you lose a villager. Lame.
I think it would be nice if the balls don't reappear in the top right corner because there's been many times I've been trying to fill over there and a ball appears out of no where and I lose a life. Also when you run out of balls, just end the game. No point in making it lose lives when you can't fill in any more.
To all of you who say it's too easy, speak for yourself. I can't get the hard badge.
