Demo v0.3 Minor Update

A minor update that makes failing at dodging a lot less punishing (and makes it easier to notice high-danger projectiles during a chaotic level), based on what I've seen players who only play Tower Defense struggle with later on in this game. Also did significant reworks on AoE projectiles as well as enemy pathfinding, based on bugs that I've been told about. If you encountered bugs during your playthrough, please report them to me on Discord! Many thanks :)

Balance Changes


  • Boss now has a limit to how many minions can be spawned onto the field at the same time
  • Boss sphere damage to player reduced by 33%
  • Missile damage to player reduced by 15%
  • Upgrading to Frosty Bumperfish now increases Bumper health by 74% instead of 48%

Visual / Audio Changes


  • Missile Skeleton now flashes a noticeable light when launching its missile
  • Missiles now play a looping sound when present, similar to Bomb Barrels
  • Boss now plays a big particle effect when dying
  • Added hit particles for cannonballs and Boss spheres
  • Added coin collect sound when outside of levels

Level Changes


  • Some tutorial reworks
  • Reduced Level 1-13 skeleton spawn immediately before first big wave

Bug Fixes


  • Fixed a glitch where if a Turret Clam was hosting a turret card when it got knocked out, it will become able to spawn another turret card after waking up, even if the previous card was not collected
  • Reworked AoE projectile behaviour so that if you stay inside of one, it always damages you at a fixed interval
    • (e.g. If you remain inside a Boss sphere, the first damage tick occurs the moment you make contact with it, while a second damage tick will not happen until exactly 1 second later; Prior to this update, the second damage tick might have come sooner depending on the sphere's life time)
  • Reworked pathfinding so that ranged enemies are better at finding the nearest tile from which it can shoot at its target
  • Fixed glitch where if Missile Skeleton is unable to reach player due to turrets blocking all available paths, it will stay still near a mountain tile that's deemed close to the player
    • (It now walks towards turrets instead)
  • Attempted fix for a rare glitch where Bomb Barrels can run out of map bounds for specific players

Demo v0.22 Patch

A small patch - Here are the notable changes:

  • Fixed a glitch where Odin can rapidly heal up by running between different heal tiles (applicable to those who hacked the game and got Heal Snail)
  • The Dev Console must now be enabled inside game settings to be useable
  • The DEMO info panel will no longer pop-up prior to finishing level 1-5 (For those who quitted the game after seeing the pop-up: You can still keep playing! - Just close the info pop-up)

Demo v0.21 Patch

We are 5 days into the DEMO release - Thank you all for checking the game out!

  • The game's OST has been entirely revamped (Don't worry, it was only tweaks to the compositions)
  • The broken in-game Discord link has been fixed
Check out the game's Kickstarter campaign if you'd missed it!

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

“The ocean awaits us to reclaim - Let the Operation Octo commence!”
- a message from Dr. Finn the Dolphin (who really needs your help because he’s too lazy to do the work himself)
