I couldn't stop playing this rhythm game since I thought its mechanics were so great and it was way more enjoyable than Touhou Lost World! I thought it was cool that you could actually battle some of the characters while playing one of the songs in a rhythm game, much as in the other Touhou games. They've done some really great collabs; I remember feeling devastated not being able to get one of the cool cards lmao. I'm still sad this one is gone but there's a new one available on steam, it doesn't look the same but go check it out!
