Biome
A quiet descent
A calm arcade game about a bioluminescent creature descending through a living water column. Drag anywhere and it swims toward your finger, settling just short of it — so your hand never covers what you need to see.
Fifteen seconds of Descent, layer 10. No sound — the game's ambience is generated as you play rather than recorded.
What you're doing down there
The water is full
Lumen Cells are the only food. Razor Cells cut where they touch — catch one with your body instead of your head and it takes everything past that point. Mimics wear the Lumen's colours but pulse fast and even, with a dark nucleus.
Nothing is wasted
A cut tail doesn't disappear. It comes apart into living cells that drift for a few seconds — chase them down and you get your length back. Every mistake is recoverable if you're quick and calm about it.
Two ways down
Descent runs sixteen authored layers and then as deep as you can stand, each asking more of you. Drift is two minutes, feeding as the light fades.
Made of nothing
No image files and no audio files ship with the game. Every organism is drawn at launch, the water is a single shader, and the sound is synthesised from one pentatonic scale — which is why the feed chime climbs with your streak instead of repeating.
