Dr. Odin, an octopus scientist, has teamed up with his Dolphin colleague to put a stop to underwater skeletons’ reign of terror!
In this action Tower Defense game, you fend off hoards of skeletons by strategically placing sea creature turrets. Beware that as your line of defense falls, this quickly turns into a game of survival where you dodge around for dear life!

Features
- Unlock Turrets: Your arsenal is filled with mechanized sea lives! Those cool inventions (such as Pistol Shrimp, Navy Seal, and Death Ray) will handle the fight. You’ll discover new turret types one after another - Figure out how best to utilize each of ‘em!
- Skeleton Enemies: Did you know that most humans who ever lived are dead? Tons of skeletons end up in the ocean, and are terrorizing local ecosystems. Fight sword-swinging pirates, poison-wielding chemists, and even skeletal dragons… Those skeletons are sure to shake up your playstyle at every turn!

- Unique Biomes: As you adventure the seven seas, you’ll add more creatures into your turret collection, and face new and exciting dangers. Adapting to changing environments is key to survival: Don’t misstep into a toxic brine pool, or forget your light in the darkness of the deep sea.
- Turret Upgrades: Skeletons will sometimes drop a variety of Elixirs. Use them to boost turrets into different forms! Will you turn a turret into a frosty ice machine, a powerful mutant, or a shadowy stealth weapon?

- Boss Fights: Special levels featuring larger-than-life boss enemies with formidable abilities!
- Awesome Upbeat Soundtrack: Seriously, the composers are amazing
- Mostly created by one person, while doing college
- a message from Dr. Finn the Dolphin (who really needs your help because he’s too lazy to do the work himself)
Operation Octo has just released! You can now play up until the first 3 biomes! \nIt has been 5 years since I started making this game - Thank you all so much for being part of the journey <3\n\nIf you encounter any bugs while playing, please report them to me on Discord ! \n\n[img src=\"https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/clans/44356379/480f0afb416228b9bf5421b0206316559c844095.png\"][/img]\n\n-------------------------------------------------------------------\n
Looking Ahead
\n
I will immediately be working on new gadgets, new shop turrets, and lots of quality-of-life improvements & balancing in the next few weeks! \n
[/*]More biomes, starting with Volcanic Ridge, will eventually be added as free updates
[/*]But before that, expect the level editor to arrive this year (Edit: erm, early next year), where you can create & share custom levels via Steam Workshop! \n

\n-------------------------------------------------------------------\n
Other Noteable Changes
Balance Changes
\n
Bolt Eel cost decreased from 50 to 45 \n
[/*]
Eels have consistently been the weakest combat turret, due to its weakness in early game, and levels never spawning too many enemies for AoE investments to pay off. A slight cost decrease will alleviate some of the early-game struggles Eel decks experience.
[/*]
\n
Bubble Parrot deployment time (turret ball toss) reduced from 1 second to 0.3 second \n
[/*]
There are reasons to reactively revive turrets in a timely manner now. This deployment speed buff will make Parrots more reliable for these use cases later on.
[/*]
\n
Mutant Bumper Fish melee damage deflection increased from 50% to 66%\n
[/*]
Mutant Elixirs are so precious, that people rarely give it to a Bumper, whom I actually consider to have a very interesting upgrade.
[/*]
\n
Lionfish spike damage to 2 targets increased from 30 to 35\n
[/*]
Lionfish is often thought of as the weakest gadget, due to it requiring very niche scenarios to be worthwhile. If you barely failed to snipe a single skeleton with Lionfish, you\'ll now still get a bit of a bonus for the placement.
[/*]
\n
Pleco attract capacity per collection decreased from 4 items to 1 item \n
[/*]Pleco collection cooldown decreased from 7 seconds to 4 seconds\n
[/*]Pleco now picks up the item that is closest to it, while prioritizing pearls inside Clams \n
[/*]Mutant Plecoattract capacity per collection decreased from 8 items to 2 items \n
[/*]Mutant Plecocollection cooldown decreased from 4 seconds to 2 seconds\n
[/*]
Pleco, the most OP turret in the game, is finally getting nerfed! This rework is mainly aimed at reducing Pleco\'s synergy with Pearl Tree. Pleco will now require a whopping 16 seconds to fully reel in a Pearl Tree\'s produce! (assuming there aren\'t other pickups that\'re also waiting to be collected!) If you bring Pearl Tree to a battle, Pleco is no longer your default choice of collector, and you might now want to manually tend to each Pearl Tree harvest.
[/*]
\n
Pearl Tree now attracts skeletons that are close to it (Forcing attacks similar to what Red Herring does)\n
[/*]
It\'s too easy to profit off of Pearl Trees. There simply wasn\'t enough of a risk to this economy investment. Now, if even an otherwise-harmless Bandana Skeleton waddles through your base, your Pearl Tree could die.
[/*]
\n
Hammer Shark can no longer demolish a Pearl Tree while it is bursting pearls \n
[/*]Hammer Shark Hammer Shark can no longer demolish Clams \n
[/*]
Recycling Clams has led to some game-breaking (but hilarious) shenanigans. Check out Eagle\'s Clamless strat . Hammering Clams demolishes how this game\'s meant to be played, and I have finally resolved to ban the option instead of trying to nerf it more.
[/*]
\n
Watchdog cost now capped at 60 \n
[/*]
Watchdog will no longer become a guaranteed stuck-in-your-hand card. This should give it more flexibility, and allow it to not be a \"total\" dead-weight to Imitation Crab decks. (I just found out that the price cap isn\'t working for now - Will patch it tomorrow!)
