In Alpha 2, I added a dev menu where you can play musics by putting in a track code. However, there are SEVERAL music tracks currently in the game that you just can't hear outside of the dev menu. So, I've decided to post all of Alpha 2's track codes for your listening pleasure!
If I stop being lazy, I will probably also post the entire Alpha 2 OST to my YouTube channel: https://www.youtube.com/channel/UCBnuiCPekkTA7RYzZ8j6_WA

Note: Music tracks don't change the gameplay in any way. It's just different music you can listen to if you wanna.
