My game project is becoming bigger, so I got to split it different files. But as soon as I use the `rungame("filename.fl")` command, I am getting an error message for the usage of `include`.  
Is there a way to work with multiple files in GameZero?

What error are you getting? It’s been a long time since I used GameZero, but remember include working.

`ERROR: LoadError: UndefVarError: `include` not defined Stacktrace:`

If I run `include("filename.jl")` in the REPL normally, it works perfectly. But when I run it via `rungame`, I get this error message.
