We love a good puzzle level. Honestly, I cannot for the life of me figure out how to solve this, so I can't comment much on the actual puzzle design, but aesthetically this ticks just about every imaginable box. Using an alien language for the codes is a good way to add more mystery to the puzzles, and combined with the vaguely industrial backgrounds and the low-quality CRT-like display the player has access to does a good job at making PAIN CONTROL BUS feel like you're tasked to solve an impossible puzzle in an alien civilization. I like this, as it adds more mystery and provides a pretty unique setting for the level.

The emphasis on the impossible part is important - it adds another layer of stress and panic as you're forced to solely rely on memory and pattern recognition rather than any linguistic skills. This is accentuated by the ticking timer and the slow, burning build of both the song's intensity and the progressive breaking down of the level as the colours shift from blue to red and the screen distorts. All of this makes PAIN CONTROL BUS a really enthralling experience (despite my absolute inability to actually solve it), and one of the most stressful levels I've ever played despite the lack of any traditional gameplay. The payoff at the end is really nice, too, as the colours fade to white and the level slowly fades away as if expressing its own sense of relief at being solved and averting whatever consequence might have followed failure. I would recommend this level for Legendary, and think all other puzzle-type levels should take notes on what I previously mentioned makes this such an effective experience.
