Your comment made my day! Thank you so much for your kind words!
I confess I know very little about mountain climbing myself - when playtesting the game I leant in a similar direction to where you ended up, treating it more as a strenuous walk trending upwards. I'm very glad the prompts led you in directions you hadn't anticipated, and congratulations on making the Summit!
I'll have a look at the weather tables and see if I can improve them a tad - I didn't think too hard about them when creating the game, assuming that the statistical rarity of getting mismatches (like hot/hail or hot/sleet) would mostly balance out. The feedback is much appreciated!
Thanks again for the wonderful review, I'm very glad you enjoyed my game!
