Just bought this great game. I heard the online was laggy but I didnt find any matches on ranked or player in like 20 tries, which is odd since the game is pretty new.. are they fixing the servers or something or is there really no-one playing?

You're not alone. I managed to find one game when I first wanted to try multiplayer, but when I wanted to join I couldn't. Maybe the host had enough of the wait. But otherwise whenever I try to find a match no one is online. I guess this is what I like to call the Lumines effect: people play it, but not online.

If you like, you can invite me, or add me as a friend so we can play. And this goes out to other Meteos players who seek others to play with.

If, when you hit Quick Match, you don't get anyone, that means you need to hit Create Match.  It can take quite a while to find people, though, since the online is so borked in this game.  They really need to start testing these things in situations other than their own LAN.
