I cobbled together a component system which allows for the creation of two types of containers. One strictly contains data, while the other one is slower but can also contain references to other components and functions. I based quite a bit of this on some of the patterns I read in “Game Programming Patterns” by Robert Nystrom, and I really recommend it if you are interested.

In addition to that, I had a “small” (massive) memory leak which resulted from me misunderstanding the way SDL handles rendering, so I got it to render stuff and clear the command queue which fixed that.

I also started a little bit on a logging system which also uses SDL, but I want to make it more natural to use and more fitting with the way I designed this library.
