Tentacle Tower Defense

(触手タワーディフェンス)

Download the demo

Tentacle Tower Defense or TTD is a fast-paced tower defense game I released back in June 2019. It's a fast-paced tower defense game. Each level has one of three goals: survival, occupation or building a superweapon. In-game, you control a group of tentacles retaking their home from human invaders.

The game is playable in Japanese, Chinese and English. It has a bonus super-easy difficulty setting, fast-track mode to skip some levels, and an auto-collect reasource function to reduce the burden of clicking.

During the final 6 months of development, I wrote a dev/design blog bilingually on Ci-en. Unfortunately, due to Blogger's restrictions, I cannot link to the store page or blog. You must find it yourself on DLsite 'Tentacle Tower Defense' (RE253657) and Ci-en 'TentacleTD' (creator/2363).

Controls and Rules
The in-game tutorial and on-hover windows should carry you through. But I'll put in a list of controls and game rules here just in case:

Gameplay Controls

• Placing Towers: Q, W and E keys select towers to place. Left-click to place them and right-click to deselect. You can also select towers by clicking on the buttons at the bottom-left of the screen.
• Resource: Left-click to gather the purple and black orbs of energy that fall down.
  • The Generator tower can also be used to generate more energy. This is crucial to supplying your defences.
• Level End (Defeat): The level ends in defeat when a single alien passes through.
• Victory Condition (depends on level type):
  • Survival: The level ends in victory when the timer runs out and all aliens are defeated.
  • Control: The level ends in victory when all the control cells have been filled.
  • Super Weapon: the level ends in victory when the SuperWeapon has been upgraded three times.
• Emergency Cannons: The final row of towers have the ability to clear a row each. You can trigger them by clicking the button above the ability buttons.
• Spells: A and D keys trigger spells.
  • A provides an AoE damage spell
  • D creates a stream of lightning that bounces to 3 other nearby targets.

UI Controls

• Time Control: The alpha-numeric keys 1 2 and 3 can be used to scale time (1x 2x and 4x respectively)
• Pausing:
  • Hovering over the Level Info on the top left, the alien cards on the top right or the Tower and Ability Inventories will suspend the game until you leave the area.
    • This can be toggled on and off in the settings menu
  • The pause button on the top right opens the in-game menu. No actions on the map can be taken while the game is paused
• Health Bars: F and G keys can be used to toggle health bars for towers and aliens respectively.
• Control Cell Numerical Displays: The H key toggles numerical displays on control cells on or off.
• Alien Cards: Alien cards are on the top right, and you can hover over them to look at the details of enemies.
  • There are 20 cards, and they represent the likelihood that type of alien is to appear. (1 card = 5%; 1 column/pair = 10%)

Gallery
The gallery has no tutorial but hopefully, it is intuitive. I'll put a list of controls again just in case:

• The gallery is split into four frames. Select a frame then select an alien from the right side of the gallery to view their animation.
• Animation Speed: The - and + buttons control animation speed, up to a maximum and minimum. Animation speed changes the voice-over attached to the animation.
• Visibility Toggles: The next two buttons allow toggling the visibility of tentacles and the cross-section.
• Climax and Reset button: Should be self-explanatory. Only one of these buttons are available at a time depending on the state of the animation in the frame.
• Clear: [X] button removes animation from the frame.
• Stopwatch: You can set a time (in seconds) before climax then hit the stopwatch to start a countdown. The speed of animation ramps up as the timer counts down.
