Thanks :)
It's actually quite hard to show the player's direction in an impossible spaces environment. There are door directions above each door, they point in four cardinal directions. If you want to go "up" on the map, choose "up" arrow above the door. If "right", choose "right".
There's one more thing, I will be uploading a new build soon which introduces arcade mode. In this mode, you don't have to use a map as the direction towards the objective is indicated with a white dot. Arcade mode also simplifies a few other things (simpler energy management + more energy distributors, no workshop room) plus is a bit shorter (it is both shorter when it comes to size and due to more straight path towards the objective).
