I feel kind of foolish now, I forgot to reset the $count scalar to 0 before calling the subroutine again. It works as intended now. :-)

#!/bin/perl

use strict;
use warnings;
use diagnostics;
use Term::ANSIColor;
use Term::ReadKey;
use JSON;

open(my $fh, '<', '/home/david/dev/linux.json');
my $json_text = <$fh>;
my $test_scalar = decode_json($json_text);

my $max = 10;
my $count = 0;

sub reddit {
        while ($count <= $max) {
                print colored ['red'], "-> $test_scalar->{data}{childr
+en}[$count]{data}{title}\n";
                print colored ['yellow'], "$test_scalar->{data}{childr
+en}[$count]{data}{url}\n";
                $count++;
        }
}

reddit();

ReadMode 4;
my $wait = ReadKey(0);
ReadMode 0;

if ($wait eq "\cR") {
        $count = 0;
        reddit();
}
