Update
Update on what I've been doing: I went back to working on the game engine and I've been making a lot of progress. My current goal is to have every part of the editor editable in the editor, which, by the time that gets done, should mean it's fully possible to make games in it :D
TLDR I've gone from having a code-centered workspace with an editor on top of it, to having the code in the editor, which allows for way more flexibility and cuts down on all the tedious boilerplate I was having to write, which was part of the reason why I wanted to write my own programming language in the first place. So now I'm just faking it til I make it :3
