It used to seem like a crazy dream to be able to develop your own game. That stuff was for professionals, guys who got their impressive computer and data science degrees at some fancy institution.
However, with time passing, you come to realize that the tools for natural game development are constantly evolving to suit the skills and needs of gamers with a dream.
Specifically, open-source engines have picked up some serious steam in the past decade, allowing everyone and their brother access to tools in which to create creative, quirky, and fun titles. The ‘open’ in open source software allows for the source code developed by a particular company to be used at their discretion; basically, they put it out there with merely a license and let creative people go to town with it.
There are fantastic open source engines out there like Godot, Panda3D, and LibGDX. Another little gem is called Duality2D.

What is Duality 2D?
Duality 2D is an open-source engine developed with its own visual editor and is entirely powered by the programming language C#.
It is an engine where 2D is emphasized, so if you are a gamer who loves titles like Castlevania: Symphony of the Night, Braid, and Rogue Legacy.
It is recommended that you have some sort of passing knowledge of C# as a coding language, as that’s the engine’s bread and butter.
A better way to think of it is similar to Unity in terms of workflow, but it is strictly 2D in development. With workflow, Duality helps you out big time, as it assists you after you define assets to determine what their function is.
You import assets by dragging them into the engine user interface itself, you then write the actual C# code to determine how the game will act, then code for the desired object itself. Having it be so simple is a real breath of fresh air.
Installing Duality 2D
Installing the open-source engine will require a few things first.
- You should have .Net Framework 4.5 installed on your system, followed by the newest version of Visual Studio.
- This step is crucial, as Visual Studio is basically where you write out the code for your game.
- After you have made sure you check those boxes, you can easily download the most recent version of Duality 2D right from the site.
Now all that remains is starting your ambitious game project!
