You start in Thomas Edison's lab witnessing the creation of the lightbulb and as the level goes on technology gets more and more advanced eventually leading to the creation of the smart phone and geometry dash and the level ends in a recreation of the geometry dash main menu
Secondary ideas
Must have
as the technology goes up you have to hold cube jumps with the year going up by each jump
Optional
The starting of the level is an animation of Thomas Edison growing up and showing his interest in inventions and the future of technology
Tradeoffs
I would pick quality and optimization because a project like this would already be more advanced because I go by if it's gonna take a while anyway why not just put a little more effort in and make it even better
