It must be tough to know so much programming, before you can ever get halfway through making a game you probably feel a need to invent a handful of low level tools.
A lot of game dev soloists prefer programming and technical problem solving over actually designing a game. Playable systems or narratives design is an entirely different beast. It requires affinities separate from the ones needed for software development. Such people will naturally gravitate towards making tools, engines and demos rather than completing an actual game. And this is perfectly fine as their efforts produce great tools like Godot :)
@DaveTheCoder I don't know much about cat clumping. I'll hereby submit something antithetical to cats - a picture of our beloved budgie
He sadly went missing recently, under dubious circumstances. People we trusted to take proper care of him while we were away for a day - didn't do so :(
As for nightmares, my worst and practically only recurring one is about still studying in the university and missing the last deadline for submitting some paperwork essential to progress to the next year. Sounds meh, but the sense of dread in this dream is enormous. I sometimes have dreams in form of first-person slasher horror carnage, but that's somewhat pleasant, and doesn't feel nightmarish at all. Often such a dream has retro looking "graphics", like old Silent Hill games or Quake 1.
