This is real fun, not my kind of game at all and I really enjoyed my time with it.
For feedback - It's real hard not knowing how many hitpoints/ stamina points climbers have, not knowing how many tiles they can move etc. I think if you exposed more about what the climbers could do next turn it would let players think more strategically.
Presentation is top notch, just that little pinch of narrative text really goes a long way.
