Parasite Boom

Features
Read full description

Possess. Drain. Blast. One tap to control, one moment to decide. You are a parasite loose inside a colony of living cells. Slip inside a cell, drain its health, and choose your moment. Single tap to steer. Double tap to explode. Blast a cell before it's too healthy — HP below 70% and you're clear to detonate. Time it in the 40-60% sweet spot for a Perfect Blast: double the score. Chain all four cell colors in a row for a Combo Heal and keep your parasite alive longer. Watch two health bars at once — your own, and the cell you're riding — and manage both as the pace ramps up. Every level pushes further: faster cells, more of them, quicker drains, and from level 4 onward, cells that change direction without warning. Level up and earn +10 HP to keep going. No clutter. No text on the cells. Just clean, fast, satisfying reflex gameplay that gets harder the better you get. FEATURES • One and two-tap controls, nothing else to learn • Perfect Blast timing window for 2x score • Combo Heal for chaining all four colors • Escalating difficulty and level-based HP rewards • Minimalist, colorful, distraction-free design How long can you keep the parasite alive?
