Thank you for the description. I played again and managed to complete the game and save Christmas! You've done well drawing everything and creating a whole world.
I think part of the issue is sometimes things looked like impassable walls to me for some reason and I didn't realise I could walk through them, but I did eventually find I could go through something to find the window up the top and then I was away, so thanks for the help figuring that out! Great job!
