I'm genuinely surprised you knew that! Huh, well, I guess that happened.
Yeah, it's technically not an anime, but I just roll with it when someone says it's anime. With the way the characters are drawn, it's hard to really know the difference. For the most part, people just say "anime" in a general sense.
I love Touhou! Well, I still need to play all the shooting games, but I played all the fighting ones, they're awesome! OWO
But yeah, the characters ARE drawn anime style... So it's hard for people to thing it's actually games >.<
It's like with Vocaloid, people will look at it and the first thing they'll ask is 'What anime is this?'... And then you proceed to explain them it's actually a voice synthesizer, and then they get confused XDD
