Nice Game. 2 suggestions and a glitch! One, I don't thinks its possible to get all the way to 10,000,000, but i dont know for sure! Two, I think you imported some of your pixel art wrong. Some things (such as the shop stand) looked kind of blurry. Finally, the glitch, when playing, my pet was about to die and they ate at the same time they died. Coon said I lost, but I didn't return to the main menu. After that my cat was immortal too.
Anyways, Fun Game
