About Project: C.E.L.L. Demo

You're one of thousands of biologists working for The Company, a megacorp obsessed with immortality. Your assignment starts at a retro terminal: run cellular simulations and search for the key to keeping a cell alive forever. Move your cursor over glucose to attack automatically. Break it down to fuel the cell and earn ATP for your next upgrades.

Keep breaking glucose before the timer runs out to push your multiplier higher. A longer combo means more ATP to spend when the cycle ends. Experiment with glucose types, proteins, and lipids. Try different combinations in your search for cellular immortality. Review your results, spend the ATP you earned, and launch your next simulation with new upgrades.

Each cycle brings new ways to push your experiments further. Explore a massive skill tree and mix upgrades from different branches. Focus on your favorite approach or try a different build for your next experiment.
