About
Rosewood Cytoglen is an offline petri-dish survival game where you drag a living cell to swim through each level, absorb the required nutrients, avoid toxin pools and hunters, and finish before the 30-second timer expires.
Each lab starts with a small player cell at the bottom of the dish. Nutrients restore toxin charge and grow the cell toward the target radius, while static toxin pools can cause Toxin rupture, roaming hunters can cause Hunter contact, and enemy toxin shots can end the run instantly. Tap to fire limited toxin shots, dissolve hunters, and keep enough charge for the next threat.
Features:
- 50 levels with local unlocks shown on the Levels screen as OPEN, DONE, or LOCK.
- Drag-to-swim control inside a rounded petri dish, with the player cell clamped inside the arena.
- Nutrient collection goals that rise from 5 in early levels to more than 20 in late levels.
- Toxin charge management: absorb nutrients to refill charges and tap to fire toxin shots.
- Multiple hazards: fixed toxin pools, patrolling hunters, and enemy toxin projectiles.
- Clear result states: EVOLVED after meeting the nutrient goal, FAILED after time expires, toxin rupture, hunter contact, or enemy toxin.
- Offline single-player play with progress, music, and sound settings stored only on the device.
- No login, ads, analytics, tracking, network features, or in-app purchases.
Rosewood Cytoglen focuses on quick laboratory runs: read the dish, swim toward nutrients, decide when a hunter is worth a toxin shot, and evolve before the timer reaches zero.
