For some reason it's really common to call this kind of project a "Doom clone" despite it not having the features that made Doom notable at the time. Honestly, it's impressive enough that it doesn't need to be tied to being a "[90s game] clone".

There was a time when any FPS game was referred to as a Doom-a-like or Doom clone. Heck, eventually even tihngs with a first person view but no shooting, or that pre-dated Doom (Doom was a step change in a few ways but it certainly wasn't the first FPS, I remember some more primative attempts as far back as the mid-to-late 80s). The current referring-to-everything-as-a-doom-clone is basically an extension of that.

That's just my age showing, I guess. For me, all 2.5D shooters are DOOMlikes. I was actually first thinking about calling it a Quake-like since IMHO that is much more well known for its multiplayer, but then I never got around to implement powerups and all the other stuff people might have expected.

DOOM was revolutionary because it switched from raycasting like Wolfenstein to a binary tree rendering system that allowed much more complex architecture.

If it's using raycasting, it's not DOOM-like...

tbh feels like OG Wolf crossed with some early text based 'first person' RPG crossed with real time updates...

I suppose if there's one frustration it's that various 8/16bit dooms are out there including asciidoom and wondering why the better UX/vis of those weren't a thing...

I'd say it's more like Angband.
