The swapping mechanic is a fun twist and it's cool that the two character's jumps actually feel different. The duck's wing flaps feel good when you have space to go left and right.
Obviously, as you say, lots still to work on, but a good first step!
Thanks! I decided to use export variables for the jump height and decided to make them be able to do totally different things. The thing with the swapping was that I initially thought about making them swap at the same place, but when I was debugging this happened, so yes; "it's not a bug, it's a feature" hahaha
