Swap and slide your way to the goal! Use the Arrow Keys or WASD to move. You will slide until you hit an obstacle. You can swap the placement of stones on your path. Press SPACE to swap which stones are active. Stones will appear in the blue boxes, and you cannot swap the stones if you are already on a blue square.

In later levels, you'll need to collect all green keys in the level to unlock the exit and reach the goal.

As you slide, avoid the red spikes! They'll push you back to where you slid from. 

If you slide into a red square, it will stop you from sliding AND swapping. Red angled platforms will change the direction you slide in based on where you collide.

If you get stuck, press R to restart the level.
