Game crushes on key input other than arrow keys

[timschwarzbrunn]

The game crushes if you press e.g. the key "k". Change in game.rs the key detection from

let dir = match key {
    Key::Up => Some(Direction::Up),
    Key::Down => Some(Direction::Down),
    Key::Left => Some(Direction::Left),
    Key::Right => Some(Direction::Right),
    _ => None
};

to

let dir = match key {
    Key::Up => Some(Direction::Up),
    Key::Down => Some(Direction::Down),
    Key::Left => Some(Direction::Left),
    Key::Right => Some(Direction::Right),
    _ => return
};

Nice game!
