This game is very fun! The sprite work and the animation, especially on the lemmings are very cute. The technical implementation could be better. I think the game would feel better if tapping the space bar to pick up the lemming and tapping it again to drop them instead of holding and releasing the space bar. I also think it would be nice to see how many lemmings have fallen off the edge so you'll know when you are about to lose. Otherwise, very fun game!
