About this game

A complete organic chemistry study app with a full roguelike deckbuilder
living in its basement. Drill every topic, push every mechanism's arrows
yourself — then descend into a lab gone wrong, where the same chemistry
keeps you alive.

STUDY — EVERYTHING BEFORE THE EXAM (AND AFTER)

• 1,000+ Practice Items: ~20 drill formats across every topic — formal
charge, stereochemistry, spectra, synthesis, and more. Built for
semester exams, MCAT review, post-bacc and continuing education.

• Push the Arrows: Every mechanism, step by step — watch each move
explained, then draw the electron-pushing arrows yourself and get graded
on them. Stuck? Hints and a worked solution are one tap away.

• Full Mock Exams: Build a practice test with pace presets and
exam-style deferred feedback, the way the real thing scores.

• Flashcards & References: 28 decks with spaced review, authored lessons
per topic, and the complete reaction library — a quick reference that
stays useful on the job long after the exam.

PLAY — THE BONUS: A REAL ROGUELIKE DECKBUILDER

• Contain the Outbreak: Something got loose in the university's
chemistry building. Descend the sublevels, requisition your deck from
the stockroom, and seal the source.

• The Chemistry Is the Combat: Reagents are cards. Match nucleophiles to
electrophiles, chain mechanisms for payoff turns, and mind the
thermometer and the pH meter — the conditions punish greed.

• An Ever-Changing Lab: Every expedition redraws the containment map —
different rooms, specimens, caches, and bosses. Every fight quizzes the
same chemistry you study.

Free to try. One purchase unlocks everything — no subscriptions, no
microtransactions.
