Building Critical Mass

Why JabMed Media’s second game is science hangman with Fact Cards — not a Plankwalk reskin.

Critical Mass is the second free browser game from JabMed Media: guess a science term before a lab reaction hits critical mass.

Why not “Plankwalk in a lab coat”?

Plankwalk proved a house formula works — short sessions, a clear fail ladder, mobile play, optional daily. A pure reskin would feel thin. Critical Mass keeps the hangman DNA but changes what a miss means (risk meter / containment) and adds a Fact Card after every round so the science audience gets a real learning beat.

What ships in v0.1

  • Classic mode + Daily Hypothesis (UTC-seeded word)
  • 50+ curated terms with short educational facts
  • Hint and Solvent power-ups, local reagents and lab log
  • CSS lab “reactor” stage (cinematic stills come next)

Play free: Critical Mass. Catalog: game page.

Pirate fans: Plankwalk is still live.
