In all honesty, I had planned to include multiple levels (and the initialization logic for the game level has already been set up to allow different layouts to be loaded at runtime), but I had to cut the whole ‘level progression’ side of things due to the time constraints (leading to just one relatively long level, instead of multiple levels of increasing complexity as I originally intended to deliver)
That said, I do intend to implement this feature once the rating period for this jam ends.
