As of ~April 2020, I stopped working on this project for several reasons.

The way I created this was quite "over done" to the point it got hard to work out how to add new features, perhaps due to trying to be an engine rather than a game. However, I am interested in one day revisiting this concept, however perhaps in a different repository rather than this one.

Originally, this was going to be a Zombie game, but I got very bored of that very quickly, and so changed the project to be a voxel game instead.

As a result of this, the code was created for the zombie game, so when I decided to switch over, the code got messy very quickly.

To combat this, I did a massive refactor in just over 2 weeks, re-creating large parts of the project.

The commit that adds the refactored code can be found here
