Snowline: a snowboarder landing past a gap on a course between snowy slopes, slalom flags ahead

Snowline

A snowboard time trial with tricks: carve through slalom gates, take the gems, and hit the kickers for spins and grabs. Three courses opened by medals: an open Meadow, a Forest with a shortcut through the trees, and Ridge, with a gap over a crevasse and an avalanche chasing you down. Medal ghosts ride beside you, and your best run becomes your own ghost.

Keyboard: A and D to carve (and spin in the air), Space to jump, Left Shift to tuck, E to grab, Escape to pause. A gamepad works too.

Lamplight: the thief on a lamplit path through a hedged garden at night, a guard with a lantern

Lamplight

A night-time heist in pure stealth: slip into a manor and take what each level is for without being caught. Keep to the dark (a meter shows how lit you are), put out lamps, throw pebbles to draw the guards' lanterns away, and pick locks while they look elsewhere. Five levels: the Gardens, the Stable Yard in the rain, the Ground Floor, the torch-lit Cellars, and the Upper Floor, where the family jewels wait in the vault and a guard who sees you rings the alarm. Checkpoints, loot, and a ghost medal for never being seen.

Keyboard: WASD to move, C to sneak, Left Shift to run, F to use (hold to pick a lock), G to throw a pebble, Q and E to turn the view, Escape to pause. A gamepad works too.

Shader Gallery: a hall of lesson shaders on plinths, the lesson list beside it

Shader Gallery

The custom shaders sample: fly through a hall of eleven lesson shaders, each on its own plinth and each a short commented lesson that builds on the one before. Surface shaders first (an unlit colour, a texture, lava, a hologram, triplanar rock, a dissolve, waves and a flag that move their vertices, the built-in PBR), then two low-level ones (a toon and lighting of its own). Pick a lesson and the camera glides to it.

Keyboard: WASD to fly, Q and E to sink and rise, Shift for speed, the right mouse button held to look, H to hide the list. A gamepad works too.
