From fruitberries newest video, Parkour Gauntlet 2, is a completely playable version without any mods.
The premise is to parkour while placing blocks to get to the other side of the course.
The map is not made by me but made by fruitberries, I just made it completely functional using command blocks and revamped a lot of things.
Please go subscribe to him, as he deserves it the most.
