    Hey, Great job on the build! The new immigration system really changes how the games plays in a very positive way. As a player, I feel much more in control of the way the game progresses. The interface works well, is easy to understand and intuitive. I’ve only played the Campaign mode so far, but I’m really enjoying it. It feels like a more complete experience. Like there’s more content to explore and dominate. Great work Michal!



    It is a good build.

There are no other games out there like KeeperRL. The game is a unique mixture of management, levelling, crafting, constructing, exploring, adventure etc. […] The possibility of interacting with other’s players monumental dungeons turn KeeperRL into one of the most promising games I’ve found.


This game is amazing! It’s challenging, fun, unique, and exactly what you might expect it to be. For an early access game it’s incredible. And the thought that there’s more to come thrills me! I can’t wait to see how this awesome game will develop even more.


Any time I touch another race, I get bent over like a cheap, overworked sex worker. I love sucking at this game so much.
