Aetherflow

Aetherflow is a silly little sandbox about bending water, snow and steam in a snowy seaside town. Pull a wave out of the sea and surf it, freeze the townsfolk (they will complain), melt everything with heat, blow fog bombs, and rocket up onto the rooftops on a jet of steam.

No textures, no audio files: the snow, water, sky and the sounds (even the townsfolk's gibberish) are all made live in your browser, with WebGPU.

What you need

• A computer with a recent Chrome or Edge (it needs WebGPU; Safari 26 also runs it). Phones and tablets are not supported.
• A mouse (on a trackpad, F stands in for the right button).
• Slow computer? Esc opens the menu: pick Low quality.

How to play

• Click the game to start (the sound starts with it). H shows every control at any time.
• WASD move, Shift sprint, Space jump, mouse wheel zoom.
• 1 2 3 switch element: Water, Snow, Steam. Then left click, R C V G X Z cast its spells.
• Q cold, E heat, right mouse (hold) to snow-surf, water-ski or ride a wave.
• T teleports around (town, lake, beach). Esc or O: menu (quality, sound, credits, reset world).
