Minor issue on Part 1 handle_keys

[nwymyczak]

let key = match root.wait_for_keypress(true);
match key {
    // movement keys
    Key { code: Up, .. } => *player_y -= 1,
    Key { code: Down, .. } => *player_y += 1,
    Key { code: Left, .. } => *player_x -= 1,
    Key { code: Right, .. } => *player_x += 1,

    _ => {},
}

has a match in the wait_for_keypress line that seems like it could be a typo.
