If anyone is looking for ideas ...
The first screen could be like opening scenes in a movie - a lot of games do this
where you actually upon hitting start button, actually start the game in that moment, looking behind the shoulder at the attacker and then cutting to a room and locking the door behind, waiting the follower to pass by. It could be a cut -scene where you actually record yourself playing that section, put it in the game, and after the threat passes, thoughts start popping inside MC head and you can exposite away on the mechanics of gameplay and goal for that section of the game.
or
The second starting screen, it could be also followed by a cut scene where protagonist sees that hand through a mist like perspective, reaching .. reaching ... while the MC is retreating and falling through a shaft inside some corridor, stirred, shaken, shivering - MC enters through a door and then you relinquish control over to the player.
