Description:
Parasite Days is a single player, pixelated simulation adventure set in a stylized microscopic world. You become a resourceful parasite surviving day by day inside living hosts. Navigate shifting organ biomes, adapt to changing conditions, and choose between stealthy coexistence or bold expansion. Evolve specialized traits, outsmart reactive immune defenses, and carve your own path through branching events. Every run offers new layouts, strategic tradeoffs, and a moody retro aesthetic that rewards clever planning and risk management.
How to play:
Explore organ maps to scout nutrient paths and identify safe zones.
Collect nutrients and enzymes to sustain your energy and unlock mutations.
Evolve traits that improve movement, camouflage, resistance, and reproduction.
Evade or disrupt immune patrols using timing, cover, and diversion tactics.
Make day to day choices that influence host stability, resource flow, and danger levels.
Spread into new tissues or jump to a new host to extend your lineage and score.
