IMUNO: Idle Immune System

Your body is the factory. Eight immune cells feed each other in a chain that
never stops: Neutrophils make cytokines, Macrophages make Neutrophils, and so
on up to the Stem Cell. Buy one cell and the whole chain runs faster, awake or
asleep.

IMUNO is a long idle game. Not a week long. Years.

FIGHT SOMETHING REAL
Every Immune Response is a fight against one invader, and you pick it. A
Bacterium is quick. A Parasite takes five hundred times the cytokines and pays
far more Memory Points. The Virus grows harder the longer you watch it, so it
rewards being there. Three invaders are on the board at a time, and the choice
is yours every single response.

RESOLVE, AND START AGAIN STRONGER
When the infection is beaten, Resolve. Cells and cytokines reset; Memory
Points stay. Spend them on the organ trees, on permanently unlocking the top
four cells, or save them for the next organ. The game tells you what the next
Resolution will cost and roughly how long it will take, before you commit.

ORGANS, NOT MENUS
The Bone Marrow is only the first layer. Each organ has its own rank, its own
install grid, its own clones, and its own Hypertrophy that resets the organ for
a permanent multiplier. The Thymus makes every upgrade cheaper and stronger.
More organs arrive over time, each with one new mechanic.

OFFLINE THAT ACTUALLY WORKS
Close the app and your cells keep producing, capped and always reported
honestly: what you earned, and what the cap cost you. No fake timers.

FAIR BY DESIGN
No loot boxes. No gacha. No random purchases of any kind. Rewarded ads are
optional and give Boost Tokens; the shop sells convenience and permanent
multipliers, each described in one sentence that says exactly what you get.
Nothing you buy is random, and nothing gates progress behind payment.

No account. No sign-up. Open it and play.
