Dan is a superhero, and Phil is a supervillain. They’re both super…something. But neither knows the secret of the other. Will they ever realize they’re in direct competition, fighting for their lives? Or will tragedy strike before they have the chance to stop it? They’re definitely both super. Super screwed.
A Concept: You play as Daniel Howell, a young half-blood wizard who mysteriously receives time-rewinding powers at the beginning of his first year at Hogwarts. He realizes his powers do not adhere to the same spatiotemporal constraints as time turners: they do not obey the Novikov Self-Consistency Principle, and can only rewind up to five minutes at a time. Unbeknownst to Dan, his powers are finite - the rate of depletion is available only to you, the player, in a meter on the right of the screen. For the first half of his time at Hogwarts, you use Dan’s powers to remake decisions to make life easier for him and his Muggle-born best friend Phil. Then, in his fourth year, Harry Freakin’ Potter returns from the maze with a dead body and life for Dan gets really dark really quickly. You realize too late you should probably have conserved your powers for the war.
There are four fixed events in the game: Befriending Phil, Cedric’s death, Dumbledore’s death, and Dan’s powers running out sometime during the Battle of Hogwarts.
Potter lives, and there’s still a chance the war might be won. Protect Potter at all costs; he’s on a mission from Dumbledore. The freedom of the entire wizarding world depends on Potter’s survival.
It’s what Dan’s been told - it’s all he’s been told before he’s thrown into the heat of the battle. Now he finds himself, abandoned by his powers, face and hands covered in grime and blood, at the door of a Potion’s classroom about to collapse upon itself. On opposite ends of the room, his best friend and Harry Potter are heavily engaged in duels with the enemy. Then the ceiling breaks - the stone falls over their heads. Dan doesn’t know a spell strong enough to levitate the cascading rubble all at once. He can’t save them both.
On your second run, you - armed with retrospection - conserve your power for the final battle. You end up saving those you weren’t able to protect the first time - you cast shields in advance, pull students out of the way of impending explosions. At the same time, you’re hurled into a variety of new situations that force you to use your power to survive. Your power, once again, fails you long before you reach the most important decision of the game.
It occurs to you then this has always been a game about futility. You are not Harry Potter. You were not there when Peter escaped, or when Cedric and Dumbledore died. You don’t know about Horcruxes and how Voldemort can be defeated. You could not have prevented Voldemort’s rise to power. You could not have prevented the battle of Hogwarts. You could not have avoided the final dilemma.
You are not Harry Potter. You may have time-rewinding powers, but you never had a chance of rewriting the course of the story.
