Gordian

Taking inspiration from The Witness, Tunic, and many other great games, Gordian is a finely crafted puzzle game full of tricks and secrets.
Tie all 21 knots as tight as possible in order to learn about topology through the rule set Gordian uses to represent it.
Click to place rope, and then click circles to move it to adjacent tiles.
Right click to undo your last move, hold to undo more.
Earn medals by tying knots as tight as possible, which unlocks more knots for you to puzzle over.
This game can be quite a challenge at times. If you find yourself overwhelmed, your brain tied into knots, just set the game down for a bit. Don't worry, it will save your progress.
Take your time. Before you know it your brain will be solving knots in the background and you'll come back with a whole new perspective.
Controls:
Click anywhere place the first dot, from there you may extend the rope in any of the indicated directions by clicking (or tapping) in a valid location. Hover over the preview dots to see where the rope will go.
For Xbox controllers you will have a cursor to move around and place the first dot. From there use the analog stick to select the next direction.
Right click to undo, hold down right click to undo further. For keyboard use the "z" key, and for Xbox controllers use the B button.
Controllers can move their cursor to the right side of the screen to interact with the list of unlocked knots.
The settings menu is in the top left, allowing you to adjust volume, reset the game, hide the UI, or quit.
