Very nice soundtrack, the setting and the concept make this pretty original !
With the retro-typed soundfonts, the bluescreen on the projet page along with the pixelated images on the project page, it reminded me of a webpage that I could have seen playing Hypnospace Outlaw (which isn't that far off from your game concept, so it works pretty greatly).
The type of retro instrumentations also works pretty nicely for suggesting that you are playing a videogame inside a videogame (like in the episode Reality 2.0 of Sam & Max : Save The World), so it works nicely with your ingame setting too.
Concerning the tracks themselves I quite enjoyed the variety of them (it helps building distinct setpieces mentally along with the page's description) and they all flow pretty nicely into each other. I think my favourites were Big City Lights (it has a great mood to it) and Arcadia, Arcade Of Light (really enjoyed the energy on that one).
To conclude, very nice soundtrack and game concept (that might come to life now that Nintendo announced Virtual Boy games on the Switch Online !), well done !
