I played Cania’s world so far, and my highlight is Cloud Capers: It was an absolutely incredible level, that was one of the most if not the most fun vertical autoscroller level I’ve played on Mario Maker. I love how you first put the player in a non-autoscroller space to introduce the concepts that you’re gonna use on your next autoscroller segment. It’s a really well realized level!!
