This is the controversial aspect of speed hacks.
The jump to version 2.2 presented a technical hurdle for modders. Because RobTop (the developer) overhauled the engine to include physics changes and new shaders, older mod menus like the famous Mega Hack had to be rebuilt from the ground up. The current 2.2 mod menus are more sophisticated; they must now account for "Platformer Mode," where speed hacks can affect not just the scrolling speed of the level, but the movement physics of the character itself. This has created a divide between "classic" speed hacking (time-scaling) and "physics" hacking (modifying movement variables). The Ethical and Community Dilemma geometry dash 2.2 mod menu speed hack
