Such a clever concept! The levels got really hard, really fast thanks to a lot of rules - perfect execution of the theme :D Sadly, all those rules got the better of me and I got stuck on a level but it was an amazingly fun experience nonetheless. I wonder how far could you push it with creating new rules without it being impossible to play :P In the future, adding some 'juice' to the game would be nice as it feels a little bland without effects right now
