Tanglewoods Red Gameplay IS THIS GAME WINNABLE?

About 20 Strong: Tanglewoods Red, from BoardGameGeek:

Something foul is afoot in the Tanglewoods. It's been weeks since you've heard from your grandmother, so you're cinching up your belt, tossing on your cloak, and throwing your trusty axe across your shoulder to venture into the heart of the woods, where her cottage is tucked away (Why does she live in the heart of the woods, you ask? Excellent question. It's super dangerous. Maybe ask her that when you get there). Tanglewoods Red is one deck in the new trilogy of Tanglewoods decks for the solo-player 20 Strong system. Each deck in the 20 Strong series is built on a basic set of rules and plays using a single set of 20 dice (as well as one single chip). However each deck adds unique rules and twists to the basic system, resulting in each individual deck playing very differently from each other. The object of a game of 20 Strong is to progress through a shuffled deck of cards, each card bearing a unique challenge. This challenge could be in the form of an enemy, a unique scenario, or some other requirement. Challenges usually require a certain number of successes to complete, which you earn by rolling a set of 17 dice with varying odds of hitting (these dice, along with 3 adjustable stat dice, make up the "20" in 20 Strong). -description from the publisher
