Thanks a bunch!
I'll make a note to add mouse releases for both of those when I push an update. I'm thinking continuing to play with, and expand, this game as a testing ground for other ideas before building anything larger with 3D in Godot. Testing the art style was one of the big things on my list so I'm glad you like it! I'm really happy with how the main character renders and want use the same technique in a more involved game down the line.
