English not supported. Perhaps sometime in the future the dev can start with an English Interface translation (Easiest and least expensive). If a fan base develops and increases, perhaps English Subtitles can be added (Most difficult and most expensive). See my explanation about translation.
Touhou already has a huge fanbase. Its just a matter of showing enough support so that Zun would consider adding in an English localization. As far as I know, Zun is the only one developing the game and his main priority would be fixes and stuff.
Lots of beloved 2hus are now playable, music is good as usual, but netplay is broken, there are no replays (or score, weird choice for an STG) and the characters are unbalanced, ranging from god-tier to almost useless. Moreover cards return again, and most characters' shots barely kill enemies. These two things are probably related, maybe it's a nitpick but shooting things is a bit unsatisfying. Also there's a bug which prevents you from progressing from stage 1 to 2 in story mode if you have a controller plugged in (virtual ones included) and which happens to softlock your game if you open the manual. This game desperately needed more development time but rushing games has been ZUN's modus operandi. It's a shame, PoFV was more fun imo.
Not just the rooster of playable characters doubled, but the mechanics from earlier games were present too.
