I spent a lot of time playing this game when I was in high-school and I owe most of the ability to continue playing it to this soundtrack. Didn't know at the time that simple tower-defense games could have amazing soundtracks, so thanks, Laura! :)
Simply put, this is one the best VG soundtracks I've ever heard and might even be a contender for best VG soundtrack of all time. 11/10 without hesitation.
Only negative thing I can say is that the OST is completely out of order for every song and some of the names aren't even what they are in game; ex: "Sunburn Island" when it's "Tan Line Island" in-game.
Not quite on par as the 11/10 soundtrack for Pirate's Curse, but still has some songs that are so funky and catchy they're guaranteed to blow your nuts off.
Note: In game it's spelled "Tassel" not "Tassle" and the song "Counterfeit Mermaids" has a typo of "CounterfeLt" on the soundtrack. Just thought I'd point that out.
