One of the harder Touhou games with also incredible music, ZUN really outdoes himself here. My only issue is a recurring issue in Touhou being Shot Balance, Reimu A is leagues better than everyone else with a powerful shot, great bomb (though MoF's awful Bomb system still holds the game back a bit), and the teleport that makes streaming homing shots way too easy. My main criticism beyond the bomb system is that you fight Rin way too many times in the second half (stage 4 midboss, stage 5 midboss, stage 5 boss, stage 6 midboss just GO AWAY RIN) , but that's minor.

Also not in the game itself but Satori Rush is a fun challenge I return to regularly.
