[Chat] Do you know "Touhou Danmaku Kagura: Phantasia Lost"?

It's a Steam game, a 6-lane keyboard-style rhythm game. But with Gensokyo added in... During its mobile game era, it was only serviced in Japan. After the mobile version shut down and it moved to Steam, it started supporting English, and after a while, it even added Korean support. I played it briefly a long time ago, but it was on my dad's account so I can't access it right now (...). I'm curious about its current status. What were the problems with this game? First off, as the title suggests, it's a game targeting the "Touhou Project" fandom. This isn't the problem, but... For "Touhou fans," the game's difficulty was too high, and for "rhythm gamers," the chart quality was too low. Seriously, the perceived "Brilliant" timing window felt tighter than Arcaea's precise (+-25ms) timing, I tell you! Eventually, the overly strict timing window was adjusted to be more lenient, the challenges in story mode were made easier, and patterns were reworked, separating them for 4-key/6-key exclusive play, etc. It's a game that's consistently being improved.
