Knock and Run. 100 Doors Escape

So you're a stickman running down hotel hallways. The basic loop is simple: you sprint from left to right, and every door you pass you can tap to knock or ring the bell. Then you keep running like a maniac before the door opens and someone tries to catch you. Each level has a set number of doors you need to hit -- usually between 5 and 10 -- and at the end there's a finish line. If a resident catches you, you restart the level. That's the core.

But the game throws stuff at you pretty fast. Early levels like Lobby and Floor 2 are straight corridors with maybe one or two angry old men who shuffle out slowly. You can almost yawn through them. Then around Floor 5 you start seeing the Slammer doors -- those are the ones where the resident bursts out instantly and chases you for a few seconds before giving up. You have to time your knock so you're already past the door when it opens. Miss the timing and you're caught.

By Floor 8 there are Double Doors -- two doors close together, and if you ring both, both residents come out. You learn fast to skip one. Also Vases appear on the floor that slow you down if you run through them. Your brain is juggling: which doors are safe to knock, which are traps, and where the vases are placed. Later floors like Penthouse add Security Cameras -- if you run under one, it triggers a locked door ahead that you have to wait for. That kills your speed and sometimes gets you caught.

The satisfying moments come when you chain a perfect run -- knocking every required door without slowing down, dodging a Slammer by a hair, sliding past a vase, and hitting the finish line with the residents right behind you. There's no upgrade system, no power-ups. Just you, your reflexes, and knowing the patterns. The game has 50 levels total, and each one adds a new twist. Basement has no doors at all -- just a long corridor with traps. Rooftop has gaps you have to jump over. The controls are just tap or press a key to interact, but the challenge is reading the chaos fast enough.

One thing that's annoying: some levels have fake doors that open automatically when you pass, scaring you but not actually chasing. The game uses those to mess with your rhythm. Also the residents' reactions vary -- some scream, some throw things, some just stand there looking confused. That's mostly flavor, but it keeps each run feeling different. The music gets faster as you progress, which helps the tension. Not much else to say -- it's a simple concept that keeps escalating until you're sweating over a level called The Gauntlet.
