Thank you for the comment and rating :3. I don't know why we recently got a notification from Itch about your comment.
We do plan to animate the waterfall!
Your comment also got me thinking about that art style you mentioned... we can most definitely try to make them, we will do our research. I love the 2.5d art style in games like Replaced for example.. If you are looking for custom tile sets, with that art style, we can work something for you my friend, let us know!
