Well... It had a great opening presentation but the shooting part doesn't feel as promising. Player shots take a long time to reach the enemies and they're actually very tough to destroy. It gets undodgeable in threat level 3 and the firing power simply isn't there to reduce the bullets.
People kinda liked earlier Touhou games as they had soft fairies that usually die with very few shots, and player's main shot delivers the kill at an instant speed which gives it a strong tempo. To me this game doesn't feel like it's being inspired by Touhou, but by shmups in general.
