I really appreciated the animations of switching between "big world" and "small world". Zooming out when the skull fly flies you around is great because you can see where your small guy is in the context of the rest of the world. Also knowing what places were the "small world" were quite intuitive and I appreciate using the same sprite in each level. I found this to be very cute and enjoyable but there was an issue that I could walk in the sky sometimes? Overall great job!
