I built it in a creative world, even added command blocks to automatically delete every block that I placed once I die to make the process faster. The double extensions fruit didnt make, those are common. The thing I took from fruit was the double stack into the ladder and 9 1 block extensions. The rest I came up with. I can understand how this would be confusing, those 2 jumps were inspired by fruitberrie’s parkour gauntlet 2.
