A LITTLE OBSERVATORY OF IMPOSSIBLE THINGS
Move a little energy. Read a little light.Keep the same molecule through every discovery.
WELCOME TO THE OBSERVATORY
Each card asks for a pair of energy numbers: mint molecule / amber sensor. Create that pair, then choose Read the light. Complete the cards from left to right.
The molecule holds 0–4; the sensor holds 0–3. Later discoveries have a forbidden pair-pulse step; transfer pulses still work there.
Keys 1–5 operate the instrument. Z undoes. There is no timer and no hard move limit. A nudge suggests one shortest-route pulse and never makes it for you.
