My first 2D game in C++ using Direct3D

My first 2D game in C++ using Direct3D

This is my first 2D game. It`s written in C++ using DirectX9 (Direct3D and DirectInput). This is a very simple Snake game. At the beginning the snake is only 1 square long and when it "eats" the target it`s length is encreased by 1 square. The snake can have a maximum of 20 squares long (each square is 20px), after it reaches this maximum length the snake is moving faster and faster. If the head of the snake hit`s it`s tail the game is over:

And here is the source-code:
