-summary: I have started work on a 2D game framework
----
-
-This is the very first devlog entry for my pet project, guile-2d. As
-the title suggests, guile-2d is a 2D game development framework for
-[GNU Guile](https://gnu.org/s/guile), a Scheme implementation that has
-the honor of being the official extension language of the GNU
-project. Guile is a language with a growing number of features, but it
-still lacks a large assortment of libraries. I like to do 2D game
-programming, and I saw a niche that needed to be filled. Python has
-Pygame, Lua has Love, but there’s no fun and accessible game
-programming library for Guile. Guile-2d is working to correct that.
-
-The goal of Guile-2d is to create an easy to use 2D game programming
-framework. Libraries like SDL give the programmer a rather low-level
-set of tools that they can use to build a game, guile-2d will provide
-high-level tools over low-level SDL and OpenGL for commonly used
-elements of 2D games: tile maps, sprite animation, particle systems,
-collision detection, vector math, A* pathfinding, etc. Such features
-will allow a game developer to very quickly produce a working
-prototype with guile-2d.
-
-Guile-2d is a framework, which means that it has some opinion about
-what the right way to do things is. The most apparent example of this
-is the game loop. The game loop runs at 60 frames-per-second and uses
-fixed timestep updates. Those that have read
-[Fix Your Timestep](http://gafferongames.com/game-physics/fix-your-timestep/)
-will know that this decision is a good thing.
-
-Perhaps the most important feature of guile-2d is the ability to do
-“live coding”. When the game loop starts, a REPL
-(read-eval-print-loop) server is started. Using the great
-[Geiser](http://www.nongnu.org/geiser/) extension for Emacs to connect
-to the REPL server, one can modify their game as it is running. This
-gives users the power to evaluate some new code and see the changes
-reflected immediately in the game window. No need to restart the game
-unless you crash it!
-
-This has been a brief overview of some of the features and goals of
-guile-2d. If this project interests you, you can check out the source
-code on [Github](https://github.com/davexunit/guile-2d).
