You are a sanitiser unit. The floor is not clean. It is getting less clean by the second.

Cleaner vs. Bacteria is a one-thumb survival shooter. Drag anywhere to move — your spray fires on its own, so the only decisions that matter are where you stand and what you pick up.

LEVEL UP AND BUILD
Every bacterium you kill drops sanitizer. Collect enough and the run pauses to offer you three pieces of cleaning kit. Stronger Formula. Pressure Pump. Extra Nozzle. Bleach Concentrate. Foaming Agent. UV Lamp. Fourteen upgrades in total, each stacking several times, so no two runs build the same way.

This is the heart of it: the bacteria scale, and so do you.

KNOW YOUR ENEMY
Three bacterial archetypes, each with a silhouette you can read at a glance. Coccus takes the shortest line to you and commits. Bacillus arrives long before anything else in its wave and dies to almost nothing. Spore walks in slowly and soaks up an unreasonable amount of disinfectant.

After forty seconds, any of them can show up as an elite — bigger, tougher, and worth triple.

BOSSES
Every thirty seconds the swarm stops and one thing arrives alone, with a health bar over its head. The Biofilm Colossus sheds fresh colonies to occupy you while it closes. The Mutant Spore covers ground in sudden lunges. The Superbug releases shockwaves of concentrated toxin at close range.

THE BACTERIA BOOK
Every organism you meet is logged, with what it does and how to handle it. Seven entries to fill in.

BUILT SMALL AND CLEAN
No ads. No in-app purchases. No accounts. No network code at all — the game does not collect a single thing about you, and there is nothing in it to collect. Under one megabyte.

Drag to move. Spray automatically. Level up to upgrade.
