1.0 Beta – Unable to install WP-Tiles beta Due to Parse Error

I recently uploaded the 1.0 beta into WordPress, but I am unable to activate the plug-in because I’m receiving the following error:

Parse error: syntax error, unexpected T_STRING in /home/content/21/7609121/html/wp-content/plugins/wp-tiles/wp-tiles.php on line 79

When I look at Line 79, this what I see on the wp-tiles.php file

function wp_tiles()
{
return \WPTiles\WPTiles::get_instance();
}

I’m not sure what to do, so any help would greatly be appreciated!
