This is the link to the most recent public release version of this game, it is not a dead game and is very much still going.
It is no longer dead after the recontinuing of the game, it is not dead anymore but it may be slower than before because of some of the team splitting into Stray Dream games, but it is no longer dead.
Edit: I do not know if it will be slower than before. I just suspect it to be because some of the team became Stray Dream Games which is a group from team bieno.
