Which is why they should have advertised something like that. This is related to Doom only in that the music and textures are the same. I'll forgive a little negativity if it comes from someone correcting a dishonestly titled article/submission.

I doubt the music was played by the device, most probably it was dubbed in post processing.

'avoid gratuitous negativity' is a thought we all need to keep in mind more.

It's actually a rule of the site,

I think it should be a rule for real-life. I've found the less negative my thoughts, the better my general outlook on life.

What is gratuitous about what I said?

Just because it wasn't Doom doesn't mean it's without merit. This is a first year University project, written in small amount of assembly, with no supporting OS.

I never questioned that

You implied it was a trivial achievement. Perhaps that wasn't your intention, perhaps you had intended to encourage, but if that's the case it wasn't obvious.

it's not raycasting though

Right, it does not seem to be a raycasting algorithm, and the author mentions of it in the youtube comments that it's a "rasterization" meaning perspective projection of textured polygons.

Actually I'm the author, so yeah, that's right
