I am fond of the chosen colour scheme and style integrated into your Christmas-themed game. All graphic elements sufficiently represent your chosen theme without leaving any grey areas. The reindeer is quite cute and stands out in your scene. The objective of the game is creative and effectively prompts the user on how to navigate through the game.
I appreciate the fact you added a help toolbar. Your icons are easy to identify and interact with. However, the way you formatted the menubar could be reworked. Consider placing the four red buttons in the middle and 3 sets of white buttons at the top and bottom to balance the graphic elements.
In addition, the snow and stars have a weird grid pattern on them. Possibly consider fixing that to a solid white colour. Otherwise, the concept is creative and with further development, has great potential.
