Instructions ingame, but... Use the sliders. Press 0 (zero not o) once you are done adjusting the sliders to submit your answers.
This game is hard, unless you look inside which please only do if you are stumped. I only have 1 level for now, but I'll make more soon. Comment below if you completed level 1 without looking inside. UPDATES :D ---------------- 5/17/15: Shared / Added level 2 / Added level 3 / Added level 4 (All of this after sharing!)
