I'm pretty good, thanks. Ah I think you're talking about that collab, it's not an official Touhou game though. But a new one just came out yesterday, Touhou 17.5 Gouyoku Ibun~Submerged Hell of Sunken Sorrow. It's a horizontal Danmaku platformer. Bringing back some old fan favorites as well.
Sorry for the late reply, I'm not really active on Pokecommunity, usually only visiting when looking for roms/fangames.
How have you been?
