Nintenthropic

Games you play with your hands. Grip Prix, a kart race for up to four, steered by holding your fists like a wheel; and Finger Guns, shooters you play by pointing your finger at the screen and folding your thumb to fire. It runs in your browser, sees your hands through your webcam, and never sends the picture anywhere.

Play it at https://nintenthropic.arthurenard.workers.dev

The former address, https://super-claude-bros.arthurenard.workers.dev, remains available during the transition. New deployments target nintenthropic; existing links and running sessions on the former address keep working.

The games

• High Noon. Golden hour in Dust Creek, and the Carver gang comes out of every window, doorway and barrel: runners, dynamite you can shoot out of the air, riflemen on the roofs, and Black Jack Carver himself. Six shots; spare the townsfolk.
• Dead of Night. Midnight at a gas station on Route 9, and the dead walk out of the fog into your flashlight. Eight rounds and a barricade.
• Orbital Decay. Four hundred kilometres up, in a space station's glass cupola, with a cloud of wreckage coming at the windows. The laser never runs out, but it heats; seven panes stand between you and the vacuum.
• Overwatch Ridge. First light over an alpine valley, a bolt-action rifle with five rounds and a six-times scope. Range, drop and wind are yours to read.

Get hit and the picture bleeds red at the edges; a few seconds unhurt and you recover (in Orbital Decay the glass takes the damage, and a pane that fails ends the game). Each game hides eight secrets. In High Noon, try the bell.

And a different kind of game, on its own page: Grip Prix, a kart racer for up to four that you steer with both hands held up like a wheel (see Play Grip Prix).

Play

Open the site in a current browser on a computer with a webcam, choose Play on the Finger Guns tile (or Race for Grip Prix), choose a game in the arcade's row, choose Play, and allow the camera. A link to a game (…/#high-noon) opens the arcade on it, and …/#finger-guns on the game you chose last. To run it on your own machine, see Development.

How to aim. Hold your hand like a pistol; the crosshair follows your index fingertip. Fold your thumb down to fire, raise it to cock again. If your hand leaves the camera's view mid-round, the round waits for it and counts you back in; after a fall, fold your thumb on the results to play again.

Reload and vent. Point past the edge of the screen (a hand swung out of the picture counts): that reloads in High Noon, Dead of Night and Overwatch Ridge, and vents the overheated laser in Orbital Decay. In Overwatch Ridge, raise your thumb after each shot to work the bolt.

The scope. Overwatch Ridge alone has one: close one eye, or hold Shift or the right mouse button, or use the Scope button in the bottom-left corner of a touch screen, and the view jumps to six times. Shift, the right button and the Scope button work with your hand as with the mouse. Your hand then pans it a quarter as fast, so a tremor is a quarter as big. Pointing off the screen reloads only while you are not scoped.

The eye adapts to you: it follows how far your eyes read open, learns how far yours shut, and keeps the scope while your pointing hand hides your face (until you open the eye, or ten seconds). A small eye beside the magazine says whether your face is seen and fills as the eye closes; Settings' Eye Test shows your own picture and each eye's reading live. With Aim Assist on, men a few pixels tall at 300 m are marked so you know where to look.

Before every game, a quick aim check. You warm up on the game's own targets (bottles along the street in High Noon, mason jars in Dead of Night, the station's running lights in Orbital Decay, steel plates on the range in Overwatch Ridge). Point your finger at the lit target and fire: the game is learning where you point, so there is no crosshair to steer, and none is shown. It ends by itself as soon as 95% of your shots would land where you aim - about six shots the first time, three when the game remembers your aim - with "Aim Set": that is when the crosshair appears, following your finger.

No camera? Choose Use Mouse or Trackpad: click to fire. The right button reloads (High Noon, Dead of Night), vents (Orbital Decay) or scopes (Overwatch Ridge, where you reload with R). On a touch screen, tap to fire and tap with two fingers to reload or vent.

Key	Does
P, Space or Esc	Pause
R	Reload (all but Orbital Decay)
V	Vent the laser (Orbital Decay)
Shift	Scope, held (Overwatch Ridge)
M	Mute

Settings — the gear in the corner, or Settings on the pause sheet — has the difficulty (Relaxed is slower and gentler, for a first evening or a tired arm), the volume, a larger or high-contrast crosshair, how steady the aim is held, Aim Assist, which camera to use, whether the camera's picture stays in the corner in play, Reduce Motion and Reduce Flashing, and, for Overwatch Ridge, Close One Eye to Scope, whether the Scope button holds or toggles, and an Eye Test. Everything is remembered in your browser; Forget Saved Aim and Reset Everything clear it.

Records. Your best score is kept for each game and difficulty, and apart for your hand and for a mouse or touch screen (which is far easier to aim). The arcade shows the one to beat under Play; the results say when you beat it, and by how much.

Nintenthropic can be installed as an app from the browser (Install Nintenthropic, or Add to Dock / Add to Home Screen); it opens full screen.
