Mountain Goats Legacy - How to play in 10 minutes!

About Mountain Goats: Legacy, from BoardGameGeek:

Each turn, roll and combine dice to race up the mountain. Get to the top to score, but don't get knocked off! If you roll the goat symbol, activate new abilities - powers that rotate every mission. As your story progresses, you'll unlock even more powerful abilities and face tougher challenges. The mountain itself might even transform beneath your feet. Mountain Goats: Legacy combines dice rolling/combining and events into a longer version of Mountain Goats. But, after the first session, more and more hazards and gameplay tweaks show up. The dice now have a goat symbol - when rolled, you'll get to use one of the unlocked player powers. These can change with every session! There's also a new system called "Courage" that greatly affects your ability to mitigate luck and refine your dice rolls. This game can be played as either a single session or a legacy game. As a legacy game, it is fully replayable and resettable. You will not be asked to destroy or modify components. The first session can also be combined with the original Mountain Goats game. -description from the publisher
