Petri: Microbe Swarm

You are a brand-new microbe. Your colonies grow cells on their own: drag from your colonies to a target and a swarm of cells flows across the host to attack, reinforce or capture. Bigger swarms win, but every cell you send leaves a colony weaker. Read the board, pick your moment, and out-grow the rival microbes before they out-grow you. Most battles last about a minute. SIMPLE TOUCH CONTROLS, REAL DECISIONS - Drag from your colony and release on a target to send a swarm; drag through more of your colonies to send from all of them. - Choose how much to send: 25, 50, 75 or 100% of their cells. - Press and hold a colony to upgrade it through three tiers: spend cells now to grow faster later. - Swarms clash in flight, cell against cell, so timing and angles matter. - Rivals fight each other too: let two enemies wear each other down, then take what is left. FIVE ANIMAL HOSTS Each world is a different animal with its own look, rival microbes and hazard: - Fish: learn the basics against your first rival strains. - Frog: toxin glands pulse on a beat and destroy swarms that cross at the wrong moment. - Bird: the lungs breathe, so the whole arena expands and contracts and travel times change. - Wolf: a bloodstream loop carries colonies around the map while you fight over them. - Whale: deep tissue in darkness. You only see what your cells can see. ROGUELIKE RUNS - A seeded, branching run map for each world: battles, elites, events, a Mutation Lab, Rest stops and a final fight. Every fight is played on its own generated arena. - Start as one of three strains, Coccus, Bacillus or Spirillum, each with its own starting ability and twist. - After each win, pick a mutation from 13: Thick Membrane, Flagella, Quorum Sensing, Endospore, Biofilm, Budding (colonies that upgrade themselves) and more. Rest stops upgrade them to level 2. - Or skip the reward for extra DNA and a one-battle boon: faster growth, faster swarms, tougher colonies, more starting cells or cheaper upgrades. - Trigger abilities mid-battle: Burst, Surge, Lysis and Membrane Wall, with upgrades. - 36 events with real trade-offs, themed on each host's body and immune system. - Runs save as you go, so you can close the app and resume later. GROW BETWEEN RUNS Unlock 30 achievements to earn Biomass, then spend it on 10 permanent run upgrades. Biomass is earned by playing and is never sold. Prefer a fixed challenge? Levels mode has 15 hand-made levels, three per world. PLAY ANYWHERE - Battles of about a minute; pause any time. - Portrait, one-handed play on iPhone. - Plays offline. No account, no sign-in. - Free to play with occasional ads after a finished run, never during a battle. An optional ad can double a run's Biomass. A one-time purchase removes ads for good.
