I'm a sucker for extra thick pixel art outlines. Really cute world and I like the transition between 2d and 3d. I feel like it would have been cool if each time the player jumped in the 3d world, their jump was higher. So by the end, they jumped like 50 feet in the sky. It would make it more fun to jump repeatedly, and it would make sense because of how much the player emphasized the jumping high after coming back to the 2d world.
