One of two Touhou games I managed to 1CC on Lunatic. It's just incredibly fun and the addition of the visible hitbox on focus is very welcome. The Phantasm Stage as a hidden unlockable was fun too and I wish Touhou would bring back more things to unlock. Some shots are straight up better than others (Sakuya A) but that's always how it's been. The border mechanic isn't really a needed life support as it makes one of the easier Touhous even easier (comes up a ton in Phantasm Stage), I don't hate it so much I wish it was gone. Patterns are more complex than EoSD and the only gameplay flaw I'd say is Stage 4 goes on for way too long.

Music is Touhou music so you know it's damn good and incredibly memorable.
