I've been playing it for a couple of weeks now, by "feeling out" the game. You can customize your keys for better control, which is a plus.
Right now, I'm plugging away at collecting all of the spell cards. I prefer playing in Story Mode, because the fights are much more epic. However, some of the stories are far too short. (Suika's story is only three fights, sadly) Versus Mode is good for a quick exhibition round, and plays out more like a 'normal' fighting game.
I agree on the need for a translation patch, but that won't stop me from playing it. The Touhou Wiki has a translation for most (maybe all) of the games. Mostly plot dialogue, which is fine.
Again, I thank you for introducing me to the series. I can't believe how much I've been drawn in.
