Thank you for playing my puzzle game, I'm glad you appreciate the aesthetics and game play! A lot of the code I write comes from years of practice and improvements, and has become a reusable stencil in my projects. It was with this stencil that I was further able to code this game.
As for the theme, In order for something to be out of control, full control needs to be established first, and slowly taken away. The sense of control was slowly being taken away from the player, as the patterns and grids became more absurd, level by level. I really hope this train of thought made sense.
Anyways, best of luck to you in the GMTK game jam!
