The Human Limit utilise insane variety of obstacles and jumps, most of which are nigh-humanly impossible. The punishment is also extremely cruel, as one fail could end your run due, this difficulty basically exceeds and tests how much a human could be capable of doingalong with the incorporation of: extreme length (similar to Citadel of Void, unindicated traps, absolutely gruesome jumps & more. Basically any element which is supposedly nigh-humanly impossible but still allowing the player to get consistent (if they even manage to get good enough) basically, these obstacles are quite janky and mostly purist. The tier of this difficulty would be Tier 18-20, this difficulty utilises a bunch of janky obstacles and extremely precisional timings and glitches, such as a mid-air corner-flip (& includes a small wrap you need to do mid-air to land on the platform). Jumps of this difficuly are just plain stupid & absurdly accurate. Even just one mistake and it could cost your entire The Human Limit difficulty tower run. However, there is some RNG included in this difficulty, but not because you need to have luck, it is because physics can mess up your run and that would not be very nice at all.

I don't really think i have much to say really now, other than these jumps & obstacles are absurdly accurate and almost impossible and require tons of effort, practice, experience, skill, accuracy, positioning, persistence, timing and a bit of luck on your side. (Revamped, previous was GARBAGE.)
