This is great. Love the idea of using this simple character. Screenshot of that character looks wonderful. I don't think it makes sense for this character to jump. The material on this character looks great and is all lined up well and the animation speed is perfect as it doesn't slide. Love the fog too.
Not sure it makes sense to complete the game as soon as the last chip is collected but you could have the player return those to a place to complete the game. Also, the menu and game intro would be great if you matched this gorgeous aesthetic. Great job overall!
