It's not available for purchase anymore and it doesn't seem to be mentioned in Mark of the Ninja store page description. Is it removed forever or I can still get it somehow?

It was removed from sale last year, some time after the remastered version of the game (which includes the DLC content) came out on other services/platforms.

Not cool. It's still "completed" in the community wishlist too.

Thankfully it wasn't pulled from libraries at least.

With how absolutely wonderful KELI has been towards GOG customers lately I almost wouldn't put it past them to find a way to screw us even after we bought something.

Amazing how they can go from being on my list of anes that sells games, both here and on console, to a name that makes me pull a Nicalis and head in the opposite direction as quickly as possible.

Gog, my Birthday will be on 8th of July. If you don't release Mark of the Ninja: Remastered Edition before 7th July - I will buy this incredible game at Steam store, you have my word! BUT if Mark of the Ninja: Remastered Edition will be released before 8th July at Gog store - I will buy game at Gog store!

Remastered is out now on GOG. -75% off if you own the original and free if you own the Special Edition. In case you still care, grab it while it's hot! ;)
