Twenty seconds on the burner.
Pour four chemicals, add up to two additives, then hold the pot between 35°C and 65°C while a flashing key changes every few seconds. Time spent in range becomes the purity score that follows the batch all the way to the bag.
- A correct key press drops the pot 15°C, a wrong press adds 3°C, and the key rotates every 4 seconds
- Hit 100°C and the batch explodes, taking the ingredients with it; the explosion can be switched off
- Ten additives change heat speed, shift the sweet spot, or add purity, and unlock across levels 1 to 7
- Purity is a 0 to 100 score graded Pure to Dirty, minus a level penalty from -30 at level 1 to 0 at level 10
