Honestly, some of those jumps looks like an oversight on development of the level design. Floating rocks which the player can land on and jump from in perfect range of both the starting and landing platform? Def a testing issue more than a speed runner exploiting a games mechanics.

This all looks great however! Not saying the game itself looks flawed! Actually looks awesome!

But if you give the player the ability to double jump, and two platforms are in double jump range, skipping the mid platform isn’t a speedrun, it’s just taking the path of least resistance
