Skyreps: Push-Up Arcade

The idea

Somebody filmed themselves playing a side-scrolling game with push-ups and it went round the internet a few million times. The reason it worked is obvious the moment you try it: the controller is your own body, and the game gets harder because you get tired, not because a designer decided it should.

Skyreps is that, built properly.

Why it is not the game you are picturing

The obvious build is the one everybody assumes — each push-up is a flap, gravity pulls you down between them. It is unplayable, and not by a little. A game like that needs roughly three inputs a second to hold altitude; a person doing push-ups produces about one a second at the very start of a set and slows from there. Gravity wins every time and no amount of tuning rescues it, because you cannot ask for more input than a body can produce.

So the mapping is positional instead. The bird’s height is your push-up depth, continuously, and there is no gravity at all — the gates supply the pressure. That turns the game into something you can actually be good at: holding a position and hitting a tempo. It also means the last ten reps of a set play very differently from the first ten, which is the point.

The camera never leaves the room

The pose model runs on your phone. A frame is read, measured and discarded in a fraction of a second — no photo is created, nothing is written to storage, and the app has no upload capability at all. The only thing that survives a frame is a single number: how far through a push-up you are.

If you would rather not point a camera at yourself, touch mode is on the home screen, needs no permission, and plays the identical game.
