Despite only 3 stars, I really love this map. It has an amazing atmosphere with it taking place on a tropical island, and I love how you used the endpoint concept that Cactus Canyon had to bring it into official TF2. My biggest complaint about this is how sometimes it's pretty hard to find where your cart is, there are so many paths that it's almost maze-like, but I feel like with enough time learning the map it shouldn't be too hard.
May I suggest if you ever decide to do a Halloween version of this, you call it "Arachnid Bayou" based on the "banana spider" found in South America? I think that'd be a really cool concept, but that's just me loafing on this too much.
Good map, hope to see more of your stuff in the future.
