Wow. I love this! Your use of the jam’s theme was also brilliant! Lot’s of people made the “inputs control two different characters” but adding a 2 second delay to that make it so much more fun and cool. You used it brilliantly in level design.
On a side note, I love how polished it was and how polished the art is in general. Clean and full of tiny details like the dust on landing! Congrats!
PS: You should totally make this into a full experience sort of deal
PPS: Did you animate the character yourself during the jam? It was very smooth
