This has potential! The idea is interesting, and the art is clean. The background moving with the mouse is a neat trick, though I'm not sure what exactly it adds to the game. It's kind of basic in it's current form, but it can be certainly be expanded in later chapters. Maybe you would need to learn about the next hellhound before you met them? I'm certainly interested to see where this goes. I hope you do more!
(also, you spelled 'fortune' wrong in your tags)
