What is it?
The same circle means different actions to different species. Test 12 symbols and three grammars, record hypotheses and counterexamples, and solve 12 cooperative missions.
Test one symbol to see its meaning acted out. The same circle means a box to Luma and a place to Tavi. Species read the three slots in different orders. Tests use duplicate props and never advance the mission. Official instructions must fulfil all three species’ goals and replies. Shared parts must be put down before handoff. Pin hypotheses in the notebook and seek counterexamples.
Tap species, slot and symbol, or drag symbols into slots. Tab/arrows and Enter control every button. Pad: directions/LB/RB choose, A activates, B closes, Start pauses.
