Logic Defense: Strategy Meets Pure Logic

Logic Defense is a "puzzle-first" tower defense game designed for quick, strategic, and challenging mobile sessions. This isn't a game of grinding or endless upgrades; it's a game of intellect.

Each level presents you with a unique puzzle: a fixed enemy path, a limited set of available turrets, and specific placement slots. The goal is not just to survive, but to find the single best strategy to win. It’s a pure, brain-teasing strategy experience.

Key Features

  • The Puzzle-Box Approach: Each level is a handcrafted challenge with a limited number of towers. You must analyze the enemy path and turret types to find the perfect, optimal placement to clear the stage.
  • Charming Visuals: The game features a vibrant and high-quality art style, utilizing the beautiful Tiny Swords assets created by Pixel Frog.
  • Fast-Paced, Bite-Sized Levels: Designed for mobile play. Jump into a level, solve the puzzle, and feel the satisfaction of victory in minutes.
  • Map Growth: As you progress, maps become larger and more complex, offering new strategic challenges.

  • Constant Strategic Evolution: The challenge never stops growing. A new, unique turret is unlocked every few levels, while new enemy types are introduced every 10 levels to force you to rethink your strategies.
  • A World to Conquer: Progress through a classic, linear level map, conquering one stage at a time. Explore 3 distinct regions as you advance: the peaceful Island, the vast Plain, and the treacherous Mountain.

Ui is moderately broken when you fullscreen pc

Seems like there's some hidden mechanic? - towers should always do the same damage unless overlapped, there's the same space between enemies after all, the same amount of time in range. Yet even as soon as level 2 that's not the case.
It's like there's some micro timing (think world clock) that makes them lose a shot on every enemy that passes them?

Maybe you lose one shot of damage on the front most enemy, that's expected, whatever - but it should not be *every* enemy coming through with one more health than they should have.

Hi! Thanks a lot for the detailed feedback.

Just to clarify, that 'micro-timing' issue isn't a hidden mechanic, it's actually a synchronization bug I've just caught thanks to you, and I'm working on a fix for it right now.

Regarding the UI, you're right; since it was originally designed for mobile, PC scaling can be a bit off in full-screen mode. I tried fixing the UI issue, but I haven't found a solution that doesn't break the game yet. I’ll be doing more research to find a proper fix.
