Definitely! Converting everything into cubic coordinates is a huge help. For example, the math for things like rotations and so on become a lot easier. (xyz -> -z,-x,-y). That would be a huge pain without cube coordinates. If i had time I would have loved to implement mouse movement on top of the keyboard input, but it's a jam and i gotta pick my battles. Glad it inspired you! Of course I hope everyone enjoys the game and it puzzles them, but having it be inspiring is even more rewarding to hear - particularly for a jam game.
