Hi. I'm really glad you enjoy my game.
There is an item that allows to move faster with two ways to make it appear in the main area, but both requires to reach part with huge maze, and that is connected to colorful blocks you can move around when approach. If you reach that area: one way to make this item appear is to get the key to one closed doors in the area with green wallaper and turn on the TV in the room; and the second one is to find stairs down in the maze and go to the library room. Feel free to note me in reply if that's too complicated for such an item.
With the signs, you need to simply interact with one of them after getting them spinning.
