Write a simple game similar to [snake][].
When a user opens the page in their browser, it should display an empty playing field with a board, current score (0), a start button, and a list of top ten past scores.
- The game field is surrounded by a border
- The snake starts in a fixed position (e.g. the center or one of the corners of the game field)
- The snake grows indefinitely, with its tail fixed at the starting position
- The direction of the snake is controlled with the arrow keys
- There are no items to "eat" on the field, just an empty space with the growing snake
- The game ends when the snake hits the field's border or its own tail
