Super rad! This is a really cool collab. My criticisms - only two:
1. Since the info panels take up so much of the screen, I really would have loved for this to extend further, maybe even have a full screen option, and have the info panel show up next to the art.
2. Some of the hitboxes need some work. Check out Quote, Skullkid, Spyro, Shovel Knight, and Servebot to see what I mean.
