This is a universal exploit called “Chetahs.” It includes player-related features such as speed and jump power adjustments (and jump height if required—both should match in some games to avoid unintended high jumps), as well as fly and teleport-to-0-0-0 functions.
It also features a GUI boombox with preset music options, so you don’t need to search for audio IDs online, though the selection is limited. There are additional features to explore within the interface.
In the GUI themes section, options like “skygraynight” and “blue sky” include custom background images created by me. Overall, the entire exploit is keyless.
