As a fan of Touhou project and modest little passion projects like this, it currently is too laggy to receive much praise. I suggest optimizing performance on mobile, as this game runs at around 10 frames per second on an iPad, let alone a phone. Truth be told, my eyes lit up when i saw the character change menu. well, the corner of it, before the game locked up.
If there’s a PC port, I would love to support and play it, but for now I have to give a neutral standpoint.
