RetroTD is a minimalist tower defense game focused on clarity, progression, and replayability.

In RetroTD, you build and upgrade turrets on a fixed path to stop enemies from reaching the end. Each run challenges you with increasingly difficult waves, while rewarding smart decisions and long-term planning. The core idea is simple: build better, survive longer, and push further every time you play.

Designed for short sessions, built for long-term progression

Over the years, many tower defense games have grown increasingly complex, packed with mechanics, menus, and systems. While those games can be great, RetroTD was created with a different goal in mind:

a game you can pick up for a few minutes, enjoy immediately, and still feel meaningful progression over time.

That’s why RetroTD keeps its mechanics focused and readable, while introducing permanent upgrades that carry over between runs. Even a short session contributes to your long-term progress.

Permanent upgrades that matter

As you play, you earn diamonds that can be invested into permanent upgrades. These upgrades strengthen your base, unlock new possibilities, and allow you to experiment with different strategies across runs. Progression is designed to feel fair, predictable, and rewarding — without forcing grind-heavy gameplay.

Fair and optional in-app purchases

RetroTD includes optional in-app purchases that allow players to speed up progression. However, all content and upgrades can be unlocked simply by playing the game. In-app purchases are never required and are intended solely as a way to support ongoing development.

Always improving

RetroTD started as a hobby project, but quickly grew into something more. The game is actively maintained, with regular updates focused on gameplay balance, performance, and quality-of-life improvements. Player feedback plays an important role in shaping future updates.

If you enjoy clean mechanics, thoughtful progression, and a tower defense experience that respects your time, RetroTD is built for you.

Feedback and ideas are always welcome — RetroTD will continue to evolve.
