Main Menu - Fun energetic happy tune, Could use a little space on the melody to help the ideas sink in a little.
Lousy Ol town - Bass solo! How Dare you!I think it's actually pretty cool, just the rest of the time it could use taking a back seat a little more. Think it just needs to hit the root notes a little more.
Onward - Very upbeat, works well!
Bonus - You lost - Melancholic track, if it's a death track I think it could use hitting a bit harder at the start, but that could also be done by sfx
Nice work!
