There will be in the future a major update that will fix some bugs, it will come out with new content, new levels and big fixes. It will require some time but I'll be sure to provide a permanent DEMO soon (Edit: the Demo is NOW AVAILABLE for FREE*).

I'm gonna provide new updates to the game soon, stay tuned!
