What the developers have to say:

Why Early Access?

“We believe receiving feedback early as possible is the best way to make games. As our previous title, Shattered Hourglass, it took 8 years of feedback to build our ambitious dream JRPG. During the process we learned a valuable lesson, always listen to your community and be open to criticism.

Castle Greyrot is currently in Alpha, which means that we have a long way to build our game and plenty of space to grow. We want our supporters to be involved in the development such as providing feedback, suggestions and new ideas.”

Approximately how long will this game be in Early Access?

“Castle Greyrot will be in Early Access until we complete every chapter and feature available. We've been working on this project for over a year and we will need at least 12 months or even more.”

How is the full version planned to differ from the Early Access version?

“We would like to expand Castle Greyrot's universe and make it grand. By grand, we plan to make the content quadrupled in size. Boss battles, playable story chapters, unlockable characters, and challenging content.

  • Over 50 Unique Boss Battles
  • 16 Playable Characters
  • 3+ Chapters with alternative paths
  • Even more secrets and random events
  • Post-game content to make you question your sanity
  • Adventures: Get to know your party members and tackle new challenges
  • Extreme Battles: Face your true nightmares and rage quit
  • Trust System: By building relationships with your party members, they will help in battle even when they are not on your team

Depending on the development and feedback for the game we might add new features.”

What is the current state of the Early Access version?

“On day one of the Early Access we have:

  • 20+ Bosses to fight
  • 2 Unlockable Characters
  • The first story chapter is 100% completed that includes 20 stages
  • The first 3 Adventures and the first Extreme Battle are playable.
  • Equipment, Merchant, Chat System is implemented
  • There are some secret stages to be found
  • All core Steam features such as Steam Cloud and Achievements are implemented.

Which is over 7 to 10 hours of content is available when we combine it all.
Every element of the game is polished and tested many times. We will continue adding new content regularly as the development continues.”

Will the game be priced differently during and after Early Access?

“Yes. Early Access price will be raised as we release new chapters and features.”

How are you planning on involving the Community in your development process?

“We're looking forward to working with the community on several topics:

Balancing the game
We want Castle Greyrot as challenging as possible, full of unfair bosses and their gimmicks are the main thing. On the other hand, we want those fights to be balanced. We’re counting on the community to help us make it possible by polishing the hard edges.

Eliminate the bugs
We are working hard to make the game as bug-free as we can. However, our bug-free experience might not be the same for the other players. CRUSH THEM BUGS!

Suggestions
We are open to any idea that makes our game a better one. You can imagine us that we are a sponge and your ideas are the water.

Translations
Our final step is to localize the game to a wider audience. This one will be tough and will take so much time for us to make. We will let the community know that we need translators in the future.”

Reviews

“Challenging is a word that pops up constantly when talking about this game, whether from the developer point of view, streamers, or reviewers. This isn’t a bad thing as the satisfaction that you feel when you make even the smallest bit of progress is unreal.”

About This Game

Castle Greyrot is a tactical rogue-lite RPG that blends adventure and boss rush elements into a thrilling experience. Expect the classic rogue-like mechanics—randomized stages, powerful loot, battle-altering curses, brutal bosses, and meaningful choices—but with one major twist: your progress is permanent. Keep your hard-earned gear, unique heroes, and upgrades as you fight your way through the ever-changing Castle.

A Living, Breathing Castle

Legends say Castle Greyrot is alive, shifting its location every ten years and corrupting everything in its path. Filled with deadly traps, hidden treasures, and relentless foes, the Castle lures adventurers inside—only to feed on their souls.

Summoned as an experienced Commander, it’s your mission to lead a team of mercenaries into the depths of the Castle and eradicate the unknown evil lurking within.



🛡 Class-Based Tactical RPG – Choose from 16 unique classes, starting with the Cleric, Thief, Warrior, and Wizard. And yes, our returning hero, the Time Mage, is here too! Build the perfect three-person squad to face the Castle’s horrors.

🔓 Unlockable Classes – Progress by mastering your current classes and uncovering the Castle’s secrets to unlock 12 additional classes with diverse playstyles.

🕵️ Secrets to Uncover – Each class has unique skills and perks that can help you unveil the Castle’s deepest mysteries.

🎲 Randomized Encounters – No two runs are the same. Expect alternative paths, dynamic events, and unpredictable boss battles. Watch out for DEADLY traps and mimic chests hungry for your arms!

🌀 Rogue-Lite Experience – No permadeath. Retry battles until you conquer them—or rage quit. Experiment with different class combinations and strategies.

📈 Permanent Progression – Every time your party returns from a successful boss-killing expedition, you’ll be able to enhance your stats and grow stronger.

📊 Non-Linear Leveling – Forget grinding! Instead of XP, we use a task-based progression system. Complete class-specific challenges to level up and unlock new abilities.

👑 Boss Rush Gameplay – Castle Greyrot is all about boss fights. Each stage pits you against 1 to 2 powerful bosses, with over 50 unique encounters waiting to test your skills.

Will you conquer the ever-shifting Castle Greyrot? Or will you become just another lost soul in its endless cycle of corruption?
