    Following http://rogueliketutorials.com/ ...but with Scala and Indigo.

    I also recently completed the r/roguelikedev follow along in it: https://github.com/davesmith00000/roguelike-tutorial

  • indigo

    An FP game engine for Scala.

    The engine's site is here: https://indigoengine.io/

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

  • Elm

    Compiler for Elm, a functional language for reliable webapps.

    It's a code-only engine for Scala Functional Programmers, and so doesn't follow the usual ECS-like paradigm, and is more like Elm (or React+Redux). Employing an immutable side-effect free unidirectional data flow approach with strict model and view separation, means it's easier to understand whats going on in your game, removes race conditions, and makes it much easier to write bug-free games. Being purely functional (if you choose to...) also means unit or property-based testing of games is a relatively painless experience (e.g. no mocking needed).

NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. Hence, a higher number means a more popular project.
