 # Dengine
 Dengine is a 2d game engine developed with OpenGL and low-level libraries in C. The main goal of Dengine is to facilitate learning from many aspects of Computer Science. Alongside Dengine a game is being built which guides the development of features for the game. Dengine is inspired by Handmade Hero, with a focus on developing as many features with minimal libraries, such that it is not too time-consuming and counter-productive to do so.

 ## Milestones
-Milestones/features/capabilities that have been added to the engine.
+Features/research that has been implemented at one point in the making of the engine.
 
-### "Handmade" API
-- Custom Standard Library: (improved as is required) (e.g. strlen, atoi, itoa)
-- Custom Math Library: (improved as is required)
-- Custom String Library
-- Custom Memory Allocator: alloc memory from preallocated blocks
-- Custom XML Parser: for reading game data config
-
-### Rendering
-- Animation playback: from spritesheets
-- Batched rendering: minimise draw calls grouped on texture & color modulation
-- Generate on runtime bitmap font sheet from font file
-- Rendering sprites: through GLEW and GLFW to OpenGL programmable pipeline
-- Rendering rects and text
-
-### Other
-- Audio API: through OpenAL and STB Vorbis for audio functionality
-- Audio streaming
-- Asset loading system using hashtables
-- Collision using AABB
-- Debug services/display
-- Input parsing, delayed, raw read
-- IMGUI style GUI: Buttons, textfields, scroll bars
-- Moveable windows
-- Primitive entity system
-- Primitive battle system

 ## Building
-Dengine is currently being developed using Visual Studio 2015. You can build the project by executing the (preferred) **build.bat** in the src folder, or simply opening the project in Visual Studio and compiling.

 Additionally, an OpenAL-Soft DLL is required which can be downloaded from the Window pre-built binaries of [OpenAL here.](http://kcat.strangesoft.net/openal.html)
 
-NOTE: Assets are not included in the repository.
+NOTE: Assets are not included in the repository. This only excludes audio as game assets are rendered with vertexes.
 
 ## Dependencies
 - [GLEW](http://glew.sourceforge.net/): Cross platform OpenGL wrapper.
