I’m dumping some of the stuff I created in the beginning of the game before I knew where I wanted to go with the art style.
The following sprites served me well as placeholder art. Maybe you’ll find something you can use as a placeholder in your own game. If any of it should end up in your final product, that’s fine as well. Feel free to modify this stuff in any way you see fit. No credit necessary, but it would be nice if you could link back here if you have a dev blog or something.
