Avoid sleepy sheeps (or throw them with coffee cups), while trying to stay on scoring area as long as you can. More coffee can be found from the coffee room, but don't get lost as the office is large and sheeps don't know mercy ;-P

I think softer, less drum-reliant music would have fit the sleep-focused aesthetic of the game a bit more. Having WASD controls alongside arrow keys would also make the game a bit more intuitive, because players don't have to switch to one keyboard layout, if they're used to the other one.
