For some reason when I’m playing this game I can’t get the tune of Frosty the Snowman out of my head!
Here is an image you might find useful. It’s in the mapthrough too but for all its ubiquity it isn’t easy to make so I thought I would get more mileage out of it by putting it here.
The blue, red and yellow are primary colours and the purple, orange and green are made by combining primary colours. Knowing this may save you some time. I would like to tell you that I figured this out myself but I didn’t, over at EscapeGame24 I got help, thanks Bat E.
