They did their usual soft release on some countries and probably fucked up and then fixed it later. If you want to try it use a vpn to connect it and once it loads you can just disconnect the vpn, so any old vpn with bad bandwith works.

The game is not bad, the art is actually quite good. Seems kinda similar to that match 3 witch game (which I can't remember the name of anymore) which was on Nutaku that disappeared mysteriously. At least the art style for the monsters and the colours for the elements/background.
