Just played it. I really loved it! Sure there are things that I hope will be ironed out but as a demo it was pretty polished. One issue I ran into was on level 2 when activating the first save point. I didn't yet have enough coins to save the checkpoint but he offered me $100 coins I think (forgot exactly what he said) for one of my lives or hearts (forgot that too lol). Anyway after that when it played the saving animation and music, the dog cowboy was still there but the frog went completely invisible. I was still controling him but I couldn't see him. He re-appeard after I got hit by an enemy.
