I didn't exactly enjoy a 5 second loop of the same music over and over again, And I didn't like the game loop but I see what you were going for!
(Also I did not read the lore, Which seems like you specifically intended for it to be a part of the experience. Which if you do have lore you should make it... clearer inside the game? I'm thinking of it being like lore inside a story game that gets explained the more you play.)
Also the page called "IT"... nyx??? which is inconsistant when connecting it to the game, And the page itself.
I personally don't think redacting a name of something to "IT" does any mystery. at least it didn't do it for me in the game.
Also cubes merging into making you do a mini-game is an awesome idea.
I love it alot!
