I love the animation style (it suits this game really well) but it makes it hard to see what has to be done and if the game didn't guide you through it would get pretty hash. short but really cute story and easy do to all the prompting. I would like to see a sequel game with similar animation less prompts (more puzzle based) and with a way around the vision problems like a flashlight(with limited battery because of the power shortage)
it'd be cool if you could interact with other painters of the era (if you did poorly your clients would go to a competitor) or if you included other aspects of Leonardo's life like his inventions, sculpting, buying better quality paints, materials canvas could increase customer satisfaction or income
