Thank you for taking the time to give us feedback about the game as well as inform us about bugs you encountered. All games need extensive feedback and it takes the help of dedicated people like you in order for them to improve, we're really in your debt 
The level editor is something we are definitely going to expand upon and we will of course take into consideration all the problems you encountered as well as implement a way to save your creations and share them right away with everyone else that plays the game. Also, if you' re up for it, we would very much like to add the level you created to the game as well.
