There is actually a snake that wears a top hat in a different episode Courage which the cowboy hat is an homage to.
I agree on the graphics... art has never been my strong point and I had a different idea in mind originally (based on the episode with the top hat wearing snake, Big Bayou) but ended up shifting right before the end of the game. As a consequence my background and menus were what really suffered but I powered through with a sort of "purposeful programmer art" aesthetic :D
Thank you so much for playing and your great feedback! I really appreciate it!
