Cool idea. I like how simple and challenging it is at the same time.
If you decide continuing, I suggest adding features like coyote time and jump height scaling from how long jump is pressed and other small things that make platformers feel a bit more forgiving and responsive. Because some times it felt a bit restricting and hard to time jumps perfectly.
But overall, I enjoyed it and idea itself is really worth exploring more in the future. I wish you luck!
