Wow! Very cool submission! I really like the idea of playing a skateboarding-mailman game while hearing the mailman talking about hoe much he loves his job lol
The production is very good, and riffs and hooks are pretty catchy, and pretty enjoyable.
One gripe i have, is i think the first 3 tracks could've been one 3-4 minute song, because they are about pretty similar things, and are more similar to each other than to Alien mail.
Overall, very creative and just a fun submission. Good job!
