From Emanuele Feronato: "In first step I showed you how to generate the first 10 levels, both with objects and with arrays generated by Tiled Map Editor.
Now it’s time to add another feature to the game: randomly selecting the starting clock. Moreover, the starting clock has a different look, with another color and a visible clock face.
From now on, I will also use levels generated by Tiled, but you are free to generate yours as you want.
I had to turn some flat images into sprite sheet to store normal and highlighted clock status in a single file, and same thing goes for the hand."
