Good concept, needs some work. I think that starting with a level just focusing on platforming is smart as it lets the player get used to the swap controls. The later mechanics were really interesting and give loads of room for expansion. Unfortunatly even ignoring the known issues with the doors there are many ways to sot lock the game which is a shame. It would also be nice to have some user feedback about how long the rope can get as when trying to judge jumps it can be frustrating not knowing if you have the distance to make it or not.
i enjoyed playing this, some great ideas here that could easily be fleshed out. Well done
