This is probably the best Touhou gacha game out there right now gameplay-wise. I'm very surprised that it took this long to get a shmup in this scale onto mobile devices. The visuals and presentation are clean and striking, the soundtrack is good (as usual), and the story seems interesting from what I've read so far. However, this game doesn't seem to have much staying power right now, due to the strange choices it has made.
The stamina system (AP) is brutal if you are starting out. Although it regens at 10 minutes for 1 AP (Max is 100), you will level up pretty quickly so you will end up overflowing. So you would start doing character stories/events to drain AP, but each run would take 15-25 minutes (no autoclear), which won't be looked at favoredly for basic dailies. If you aren't proactive, I'm sure you'll just end up with too much AP that is kept everyday, and you will end up wasting a bunch of regen everyday.
Then there is the shmup gameplay. Using 30 AP, you will play 5 unique stages, and you just clear them. However these 5 stages are only unique to the story. If you were to replay the story, you play the exact same 5 stages, which will become monotonous as you grind that. You will probably say, "Isn't that just mainline Touhou?". There's a difference between playing stages because you feel like doing it and playing stages because you need to use AP so that it doesn't cap. You will end up just burning out at some point if you keep that mindset for a while.
The characters are also pretty important when playing a Touhou game as well. You will have Reimu, and then a free character chosen at random. The only way to obtain new characters is through the gacha, which is a bad decision in my opinion. As its a shmup, there is already little variety in how its played: shoot and dodge, so having them being locked behind that isn't nice to say the least. On the plus side, there isn't a big power gap between the worst and best character, so you can play whoever you like without worrying about being suboptimal.
Then, there's the gacha. There is a character and weapon (card) banner: 2.5% to spark a 5* and 200 pity to guarantee. The banner characters are limited, so you won't be able to get Aya anymore as of right now. If you obtain the banner character before 200, the pity will reset. Strange idea, it means if 2 banner characters are running, you can't use the guarantee to get the other banner character if you already got one early.
As for the endgame, it's where it gets polarizing. There's only a couple things you can do. First, the Tower, which is basically a long list of stages that increase in difficulty. Next are the character stories and events, only good for if you need a better kit for a character, or for event currency. Lastly are the boss rush stages, done once a day, but you can select the difficulty you want. There isn't much depth put into anything besides the gameplay.
In conclusion, I still think its a good Touhou game since it is "free", and it's worth a try if you have ever played any mainline Touhou. But I wouldn't recommend playing it for the gacha itself, unless you really want a character you like. I can appreciate the amount of effort put into this, but as I stand:
Good game, but keep playing only if you feel like it's still fun.
Edit 1 (11/29/23): With the first event now being released, there is now another source to use AP (Stamina), although you would still need to do the usual 20-30 minute runs in there as well.
Edit 2 (12/11/23): Since I've reached level 22, the highest level as of now (not anymore 12/14), I added a category for the state of the endgame. They also fixed linking accounts and the loading glitch, so I've removed that entire paragraph. I've decided to overhaul most of the review since its 3 weeks into the game, and I've gotten out of the honeymoon period.
El drop rate teórico es favorable y el BGM resulta destacable.
Cabe mencionar que la animación L2D de los personajes se puede activar al asignarlos al lobby.
En cuanto al aspecto técnico, en reiteradas ocasiones la app dejaba de responder y tuve que reiniciarla. Además, pude notar que le falta compatibilidad con algunos dispositivos.
Al final sí me parece un producto que vale la pena probar si los RPG tipo shoot 'em up con desplazamiento lateral y/o si la franquicia Touhou son de interés. Sin embargo, considero que tendrán que mejorar su rendimiento.
Por último, pienso que puede terminar opacado por títulos similares que están más pulidos como Sky Fortress: Odyssey.
