This was the first thing I truly couldn’t figure out and came looking for help (also, the in-game hints didn’t help at all. they said first to look at the arcade machine WHILE I was literally looking at it lol, and then to take a picture of the tree. I know! I was having trouble with what came next!). The first hint was just the arrow, so it looked like it just pointed to the first colour, and I kept trying to go from the bottom (white)! I tried yellow, then I tried orange ‘cause I took into consideration the circle rotating the arrow, but I didn’t think that it was going from one colour to another. This could be communicated better.
