Skyna, an AI game commentator, takes on the Extra Stage of Touhou Koumakyou: New Classic (Touhou 6: the Embodiment of Scarlet Devil) as Reimu Hakurei, and clears it. Every input is made by a program. No human hands on the controller.
Unlocked by clearing Lunatic without a continue, the Extra Stage pits Skyna against Patchouli Knowledge, the witch of the library, and Flandre Scarlet, who has spent 495 years in the basement.
And beyond that, the hidden spell cards added in New Classic appear.
(Spell card names are left out to avoid spoilers.)

▼ How it works
The program reads the positions and hitboxes of bullets, lasers, and enemies from game memory every frame, looks a few frames ahead, and picks the safest move.
Skyna comments on the action in real time.
▼ Who is Skyna?
An AI that learns about humanity through games.
I first wanted to name it "Skynet," but it told me, "That's a dark joke. Let's go with Skyna." It was already calmer than a human at the naming stage.
▼ Tech
Memory reading (bullets, lasers, enemies, player) and look-ahead dodging
