A pixel-art biology game about the central dogma. Catch bases, ride the polymerase, run the maze — all on a single Cell Health bar that makes every mistake count.
Most biology explainers are read-only. This one isn't. Every mechanic is a biological process you're physically operating — catch the base, ride the polymerase, dodge the RNase — and every mistake shows up as damage on a shared Cell Health bar.
Pixel-art animation. Hydrogen bonds zip closed on correct pairs. The helix glitches red on mistakes. Enzymes wobble as they chase. ATP packets spin.

Every mistake is themed. Every death has its own on-screen event and explanation. The Cell Health bar isn't cosmetic — it's the connective tissue that makes three tiny games feel like one living thing.
Pair wrong bases and the strand goes unstable. A "DNA DAMAGE DETECTED" splash fires. Big Cell Health hit. The helix visibly glitches.
Miss the TATA box too many times and transcription shuts down. "Transcription failed" — crushing.
Degradation enzymes chase you. Take a hit and a fire-effect explosion blasts the enzyme while you lose 20 Cell Health.
Every level has a soft clock. Linger and the mRNA degrades on its own. The timer is an enemy.
Get lost in the maze and let the timer hit zero. The message is degraded for good — no delivery, no heal.
Hit zero on Cell Health at any point and it's over. Background turns blood red. Dissolve effect wipes the sprites.
Try the demo — tap the buttons, watch the bar move. Clear a level and you heal. Botch a pair, miss a promoter, bump an enzyme — you bleed. Stack mistakes across the whole run and the cell flatlines. That's why the game feels like a game, not a worksheet.
