I can see that you keep improving in the right areas, such as your animations, art style and even the way you use audio in your content. Since this is a game however, I feel that you have failed in making it accessible for everyone. A puzzle game such as this should have different difficulties so that it can be enjoyed by everyone and not just the small group that are able to beat it in its fixed difficulty. I understand that some games, specially retro games were made with a fixed difficulty so that players had to, as all the dark soul memes say "get good" but with modern game design I feel that puzzle games such as these should give their players the option to pick their difficulty. I am not very good with puzzle games as I play too many action games but I can still tell that this was very well made. The only criticism that I give you is just that, should you decide to create a new puzzle game to add a selection to the difficulty so that everyone may enjoy it. Other than that I hope you continue the good work.
