Honestly I feel you're selling yourself short in the description. The game isn't bad, only problem I really see is the fact the shadow merge together sometimes without the game checking *all* you click to see if you got at least one correct.
Honestly the mood of the game kinda drew me for some reason? Like I wanted to keep playing out of curiosity for whatever the ending was cause it was rather depressing seeming. And while I didn't understand it (non-Touhou aficionado), I enjoyed what I saw.
