For the risk-token total you count only the rope card's upward movement value; during the action phase you then choose whether to use the up or down value for actual movement (count up for risk, pick direction for moving). (pages 4–5)

No — movement points from a single card may not be divided between two climbers (you may use multiple cards on one climber, but one card's points must be assigned entirely to one climber). (page 5)

The maximum climbers per space depends on player count and altitude and is shown on the board; a climber may pass through a space that is at its maximum occupancy as long as they do not stop there. (page 5)

Acclimatization checks happen after the action phase each turn (phase 4); apply space modifiers, tent (+1 if same color tent), and weather penalties, cap acclimatization at 6, and any climber whose acclimatization drops below 1 dies (is removed and scores 1 VP). (pages 8, 12)

No — victory point markers record the maximum height reached, so when a climber goes lower their victory-point marker stays at the highest value they achieved. (page 6)

Placing a tent costs the space's entry cost in movement points and a climber may place only one tent in the game (spaces may hold multiple tents); when using a rope card only its upward movement points can be spent to place a tent. (page 6)
