The dream of a water cup is to fill it with water. Our task is to draw lines to guide the flow of water, fill glasses, fulfill its wishes and make it smile again. We have a large number of checkpoints and brain holes, each of which has different solutions, but we still hope to solve the problem at the lowest cost. Let's wait and see if we can get all the stars and make the water glass smile again. Characteristics: The water cup has its own expression, we hope it will become happy! Draw lines directly on the screen, the operation is very simple! Checkpoints are constantly updated, and we will continue to create the most interesting checkpoints! But it is very challenging to achieve the goal in the simplest way. You can change the style of the pen and choose what you like!
