Play it in the browser! https://lambdahack.github.io

LambdaHack is a Haskell game engine library for ASCII roguelike games of arbitrary theme, size and complexity, with optional tactical squad combat. It's packaged together with a little example dungeon crawler in fantasy setting that can be tried out in the browser. (http://lambdahack.github.io --- It runs fastest on Chrome. Keyboard commands and savefiles are supported only on recent enough versions of browsers. Mouse should work everywhere.)

To use the engine, you need to specify the content to be procedurally generated. You specify what the game world is made of (entities, their relations, physics and lore) and the engine builds the world and runs it. The library lets you compile a ready-to-play game binary, using either the supplied or a custom-made main loop. Several frontends are available (SDL2 is the default for desktop and there is a JavaScript browser frontend) and many other generic engine components are easily overridden, but the fundamental source of flexibility lies in the strict and type-safe separation of code from the content and of clients (human and AI-controlled) from the server.

Please see the changelog file for recent improvements and the issue tracker for short-term plans. Long term goals include multiplayer tactical squad combat, in-game content creation, auto-balancing and persistent content modification based on player behaviour. Contributions are welcome.
