I think it's up on the Play Store now, or at least an app that looks like it has been uploaded by the Pokemon company.
EDIT:
OH GOD WHAT IS HAPPENING
Double Edit: Oh, I think it's because my locale is English or something. Because I get this when I hit where start should be:
And then it tries to get me to accept a ToS that doesn't have an English version (not found on the Server) and then I can't do anything. I'm going to see if I can change my locale....
Edit: In the mean time I think I'm pretty sure it won't start up if you have root enabled. Just stays at a black screen and never tries to connect to the server.
SUPER EDIT:
Yeah, changing locales fixes it. And everything seems set up for Japanese beta testers, it got in game after the ToS. It's only through level 30 as far as Google Translate can tell me, and you participation and completion of all 30 stages will get you a special reward in the full game.
Gonna try changing my locale back to English, because I'm having fun.
Probably final edit for a bit:
English seems to be working alright in game... So now I'm gonna just play it. If there's anything else interesting I'll screenshot it.
Interesting Edit:
I think this is new?
Aldo for some reason the coin stage is currently available and Meowth does the coin disruption if there's 2 combos instead of 3, along with Mew and the Rotom daily Pokemon stages. (Currently on Heat Rotom.) Otherwise the game seems up to date with the 3DS version feature wise, it's got the seperate heart counters, super catch power, and the Pokemon info after catcing them. Also, the gift box icon is for gifts they can send you, like the daily stones/orbs in other popular phone games. (P&D, Monster Strike, etc.) Currently they're giving out 10 jewels, but there's no English message for the full details.
Final edit for tonight, probably:
The English text seems to be taken from the 3DS version directly where applicable as the Mew and Heat Rotom mention end times back in March.
BREAKING NEWS EDIT:
The Mew stage costs 2 hearts to play.
