I am in the process of making a painting game and the hardest part is the actual gameplay. The objective is to complete as many paintings as you can in one minute. There'll be a picture on the right you'll have to copy. I am not going to use actual lines to paint but instead i'm going to have the player choose their colour from the colour palette then when they click specific parts of the easel it will change colour and form the image. I was thinking of doing this by having white sprite sections above the image on the easel and when clicked they will destroy and reveal the different colours of the image. Any tips? (Sorry for long paragraph)
