As the paint god, you need to draw lines on the canvas to lead stickmen to the magink factory. Stickmen with different color fuses together to create new colors, but be cautious not to generate unstable ones that contaminate your canvas.
You are the god of paint. To paint the canvas world, you can only paint using colors processed by magink factory. The factories are ancient technological constructions which already exists in the world, so you cannot move or create them. There are also randomly generated colorful ink pits around that randomly spawn stickmen. What you need to do is use your paint brush to sketch routes for them, and finally lead them to the factory.
