This game has been designed to teach colors. Yet there are a lot of problems with it. Correct them by checking these: -Is the color mixing working for all the colors correctly? Are they any missing ones? Or ones resulting in wrong colors? -Check looks. Do hide/show work correctly for each color? -When drag&dropping the colors onto the painting, do we get correct results? (Check the reference picture) -Have the loop blocks been inserted correctly? -Do all the main colors go back to their correct place after color mixing? -Are they any weird transitions when clicked on some colors? Get rid of them if necessary. PS: You don't need to do any corrections in "drag mode" and "if not" blocks. They are working properly.
