The idea is awesome! Great use of the theme! This could really be it's own full game!
Sadly we couldn't figure out the second door level (the one in your screenshot), try as we might! :(
It wasn't really clear at first which moves the player does what which not. Maybe do some color coding here? Same with the ground, at first we mistook the ground for wall tiles.
Much love, great job! Awesome puzzle ideas!
