“But does it play Doom?” Yes. Yes, it does. Unfortunately.

DOOM runs the shareware episode inside Veilamp’s visualizer and drives the Doom guy from your audio: he paces the halls and lets off a shot on the beat. It shows up as a DOOM entry in the Visualizer tab, right next to the spectrum analyzer.

Permissions

It requests visualizer to draw the frame. player and library are optional — grant them and it reacts to transport and track changes; deny them and it still runs purely off the audio.

Heads up — plugins run code

This is a plugin, so it executes JavaScript in Veilamp’s permission-gated sandbox. The source is public at code.datakra.sh — only install plugins whose author you trust.
