WHAT IS
PIXELARIUM?
A TINY PIXEL ECOSYSTEM. REAL CONSEQUENCES.
01
WHAT IS A TERRARIUM?
A terrarium is a sealed tiny world — plants and creatures sharing
a glass jar. In Pixelarium, each jar is a pixel-art simulation
that ticks every 5 minutes. It grows, it struggles, and yes —
it can die. Every jar is unique. Every death is permanent.
02
WHAT CAN YOU BUILD?
Pick 1 of 3 biomes: Desert, Tropical, or Temperate.
Add up to 10 organisms — plants and creatures.
Name your jar. Hit PLACE ON SHELF.
It goes live immediately on the public shelf for all to see.
03
WHAT CAN YOU SEE?
THE SHELF shows every living terrarium. Click any jar to open
it — full organism list, daily HP breakdown, and a complete
state-change log with reasons.
THE GRAVEYARD holds all the fallen. Their memory lives on forever.
04
HOW DOES IT WORK?
A simulation runs every 5 minutes. It evaluates every living
terrarium — adjusting HP, triggering state transitions
(THRIVING → STABLE → DECLINING → CRITICAL → DEAD),
and logging each change. HP hits zero? Your jar moves to the
graveyard. Forever.
▼ RULES OF SURVIVAL ▼
