I don't think so sorry, it's been so long since I worked on this I think I've forgotten how to make a level pack!
That is a real shame, I would love to have some more to solve! I think being a bit short was the only downside of this game. I would even be prepared to pay a little to get some more levels. Is there any way we could make you reconsider to check it out and to create at least one DLC pack? Thanks in advance for understanding and for the great game!
