In any case, Touhou Lost Word is a turn-based RPG featuring what so far appears to be some classic Touhou characters. Much in the vein of Fate/Grand Order and Magia Record, Lost Word utilizes smallish character sprites performing attacks on screen, in this case with the attacks resembling those seen in actual Touhou Project games. They're also similar to those games thanks to this game's equivelant of Craft Essenses. It appears you get characters and "Craft Essenses" out of the gacha, though characters seem to either be incredibly rare or I just don't understand the gacha system all that much.
In any case, the game has an unusually long prologue with the main story, rendering a legitimate team meaningless as you're forced to use pre-made teams for the whole prologue. Of course you can use your own team in mobile trademarked challenge stages for earning power up goodies, but no real stages until you pass the prologue.
The game seems generous at first with the premium currency, though again I may not fully understand the gacha so take that with a grain of salt. The artwork is great and the soundtrack is fantastic, with the music constantly changing and even showing the name of the song and the artist behind it as it switches which is a neat touch. It clearly has a hefty story if the prologue is so bloody long, and in any case is a huge step up compared to the lack of stories in other Touhou mobile games I've played up until now.
Overall, I quite like this game and very much recommend it to fans of Touhou and fans of mobile games with more strategy required than most similar games.
