I'm must admit I like math so it was a pleasant suprise to see a game about topology. I never saw knot theory mentioned in a video game before.
By playing I learned how to form a a trefoil and a figure-of-eight, so congrats it was nice learning something new!
Concerning the game itself, I did have a slight bug where the tutorial repeated itself, and tutorials could overlap each other if I met the objective before finishing the current dialogue. But I really enjoyed the tutorialisation with the narration, and also enjoyed the visuals and feedbacks of making loops with intersections.
Great job I had a good time!
