Great Job! I like the colour scheme.
The gingerbread man and the icing stand out in the dark room.
I like the shape and decor of the tree, too.
On the start-up menu, there is a good choice of words and the game menu, a great UI, colour choice, and positioning.
The "back" button has only a different colour, which helped me mix up with the setup button.
The thing I can suggest is a font choice, it is slightly tricky to read for me, but the font suits the scene.
Well done! Looking forward to seeing your game next!
