I didn't added some options from your wishes, i have only some i thought were needed, but in there you can find that
Float/Fly option, read what is in that IMPORTANT thingy, there's multiple parts in this game where using a jump multiplier will get you stuck, though floating, set at the right speed changed in that script will work great.Also, there's cheats for all game modes, for all characters.Is for the latest steam version, 64 version, launch the game through the steam launcher's options.
Have a stupendous day!
