Basement Escape Code

I’m trapped in a dark, eerie basement where the only way out is through a locked door that requires a code. Each button on the door's panel has a three-digit combination, and at level one, only one button is correct while the other is wrong. As I progress, the levels get harder, with more buttons—two correct and two wrong. To find the right code, I must explore the blood-stained basement, where strange markings near pools of blood reveal three-digit numbers that might unlock the exit. But I’m not alone. A tall, faceless man in a black suit follows me everywhere I go. His towering figure and heavy, unnerving breaths send chills down my spine as he looms ever closer with every clue I discover. Time is running out, and I don’t know how much longer I can evade him.
