Devlog 1: Logic Defense: Strategic TD
A fast-paced, minimalist tower defense game where every level is a puzzle, and every placement matters.
Hey everyone! We are hard at work on Logic Defense, and we’re excited to share where the game stands right now. We have been moving through several internal builds, currently reaching v0.5.4.2, and our main focus is making the core gameplay feel solid and fun.
World and Content
The game currently features three regions: the Island, the Meadows, and the Mountains. As you progress through the map, you’ll encounter various landmarks—some are small villages, while others are different strategic points along your journey. We are planning to expand this world with new regions in future updates.
Your main objective is simple and classic: stop the enemies from reaching your base. Right now, there are three different types of goblins you’ll need to defend against. While we are currently focused on these core enemies, we plan to introduce more variety and new enemy types as we add more levels to the game.
Gameplay and Mechanics
Logic Defense is all about strategy and how you manage your defenses. The core gameplay involves building towers along winding paths to stop incoming waves of goblins. A major part of the strategy involves dealing with the environment; obstacles like trees and stones block your line of sight, meaning your units cannot fire through them.
Furthermore, towers themselves act as physical objects. If a tower is placed directly in front of another tower’s field of view, the tower in the back will not be able to see or target the enemies. You must also navigate terrain constraints, as certain areas like water or rocky ground do not allow for tower placement. This forces you to plan your layout much more carefully to ensure every unit has a clear line of fire. Success depends on selecting the right variety of towers and positioning them strategically, as different tower types must be utilized effectively depending on the specific enemy types and the quantity of the incoming waves. The gameplay is also deterministic, meaning enemies and towers will always behave consistently, allowing you to perfect your strategy for each level.
