Really cool puzzle game !
It took me a couple levels to understand what swapping character did exactly (as in flip the platform you're on + flip the other character no matter the platform) and even after reaching the end I'm still quite unsure how to properly think about the consequences of a swap to find the solution haha.
Though there still were several levels I completed by using brain power instead of swapping about until it works out :)
I tried cheesing it by reaching both gates with the same character but you properly blocked it.
Great visuals, and the tutorial was good too !
