I was wandering on the archive, listening to the various albums he made, and then I've read his page on wikipedia to know if he made other songs, discovering that every album he made is on the archive, except for what wikipedia called "Bounustracks". The album should contain some tracks that accompain four albums, but I can't find it anywhere. Where can I find it?

(Sorry if I made some mistakes, english is not my native language)

I come across the existence of this game only today, in a forum about different Niffla's games, but the original site is dead, so where can I download the game? Can someone who has already downloaded it pass it to me?
