Slide Down

A descent through a futuristic tube where gravity supplies all the speed. There is no throttle and no brake; you accelerate continuously, and the only decision is lateral positioning against a sequence of openings and barriers that arrive faster the longer you survive. The interesting demand is how far ahead you have to look. At the speeds this reaches, reacting to the nearest barrier is already too late, so the game is training you to read three obstacles ahead and plan a path rather than a dodge — and the players who get deep are the ones who have stopped looking at the thing in front of them. That shift in attention is the whole learning curve. Runs last under a minute and restarting is one press, which this difficulty requires. The visual design keeps the openings unmistakable against the tube, which is the only thing that matters in a game judged on reading distance at speed. It plays with two or four inputs on a keyboard or a touchscreen, needs very little from the hardware, and is honest about being a short sharp reflex test rather than anything more.
