Consistent stupidity

Nummels may be dumb, but they're predictable. When they see a ladder, they will always climb it. If they find some gum on the ground, they'll stop and chew it. If they fall in the water, they will stop breathing. It's up to you to move things around so that your litter of Nummels can make it through each level to the exit.

Go fast for the best score

On most levels you can take your time and set everything up before letting them loose, but to get good scores and unlock all the things, you'll need to go fast. Each level has a leaderboard that's ranked on saving all the Nummels the as fast as possible.
A few Nummels may have been harmed during the production of this game.
