To start flying, run fly.lua.
Simply hold shift to fly in the direction you're looking in.
If you are moving downwards too fast, you should be slowed down.
This system is not infallible, especially in high-lag environments like SwitchCraft.
Please do not copy GFly or related programs without permission.
