Thanks for the thoughtful feedback! it means a lot! The beautiful background is a single art piece made by Mercisla (you can find her portfolio on the itch description) and it as all the other assets and code in the game, are up to grab for the whole community. I really want to tidy up the read-me (not only decorations, but a small guide through the code) and the code itself, so it can better serve as a learning project for anyone interested.
Great insight on the tutorial! I will probably be changing it, incorporating your suggestions in the near future. Thanks again!
