Yeah honestly the chunk generation gimmick was supposed to be expanded on a bit more, and originally you had extra collectibles that you'd have to go out of your way to collect (and which would be the "harder path") that would act as a variable difficulty slider, increasing the difficulty of chunks that'd spawn for the player. However getting actually balanced chunks working was a bit of a pain, and there weren't enough chunks in the game to warrant such a thing.
I also think the red around the screen is a bit too much, and originally the level would be randomly generated again once you died, but because of the aforementioned issues and still wanting players to be able to see each chunk at least once, I ended up not implementing it. Hope you enjoyed regardless!
