The way you have the code I think the easiest solution would be to change the meaning of the LVLx constants from "the ID of the level" (where most likely LVL1 == 1, LVL2 == 2, etc.) to "is the debug for this level turned on?". So that you could change your debug statements to 

debug "this..." if LVL1;
...
debug "that .." if LVL3;

You'd have to change the debug() subroutine to just 
sub debug {
  print "$_\n" for @_;
}

and make sure the LVLx constants are defined in time ... either by enclosing the debug level setting and constant definition in a BEGIN{} block or by doing that in a module you use on top of the program. Something like 
BEGIN {
 ... read the levels that should be ON to %debug 
 for (1.. $count_of_levels) {
  eval "sub LVL$_ () {$debug{$_}};";
 }
}
