How it plays
Pick a wall. It becomes the floor.
The Anunnaki cannot take a single step. You choose one of six directions, and the Anunnaki and every loose stone fall that way until something stops them. Find the key, then reach the door.
Everything falls together
Basalt stones fall with you. Drop one in the right place and it becomes the step, the wall or the stopper you need.
Speed breaks stone
Fall three cells or more in a straight line and cracked stone gives way beneath you.
No fall is final
Undo any move, as often as you like. Hints are always free. Fall off the edge and you are lost to the clouds, until you undo.
Six ways down
On a phone or tablet, drag from the Anunnaki toward a wall and let go. Z undo · H hint · R restart

A lyre melody over warm pads and a soft frame drum, composed live by the game and never the same twice. Turn on sound at the top of this page to hear it.
Every room has an answer
All 100 rooms are checked by the game's own solver, so none of them is impossible. When you are stuck, a hint shows the next step.
