Are there any ways to switch the .bb file ingame, without use of functions?
Like, if I could use files like this:

intro.bb
level1.bb
level2.bb
bonuslevel1.bb
endingscreen.bb
etc...

, so when I want to change level, it passes the globals, and loads level1.bb (so level1.bb keeps all loadingscripts for loading that level, and that level's mainloop). I won't use Function for that, because that has limitations. Any ideas?
