I will add comments in there soon (for now figure it out...)
This is really just for me and my games I make (none of them are released at all, still in creation.) It's a really fast pen engine that I created and I'm adding new configurations weekly or so, still not finished but I got to v0u6 (Unreleased version 6) before I decided to upload it, that does mean I updated it 6 times before uploading it to scratch. Anyways, I'm always thinking on making it faster and all the optimizations I can add to the engine, I still don't think it's done and I will make a video tutorial of some sort on this. Aldo might post updates on a separate YouTube channel of the game development (I'm also working on a programming language but no relation to the rendering engine... Yet :) .... Okay, now there is ;)... )
