Rating Summary:
This is an adventure game in which players assume the role of a knight (Graham) as he navigates the kingdom of Daventry. As players explore the open world, they solve puzzles, interact with characters, and engage in various tasks. Some scenes allow players to aim a bow and arrow at goblins or a dragon; goblins are depicted throwing spears at the player's character. Puzzle fail-scenarios depict the player's character falling into chasms or a river, being crushed by a boulder, and getting struck on the head with a mace.

King's Quest brings adventure gaming into a new era while staying true to what made the original games beloved; the unforgettable storytelling, wit, puzzles, and of course plenty of ways to die!
Select between the noble pillars of Bravery, Wisdom, and Compassion to see what rippling effects these choices will have on Graham’s journey as well as later chapters.
Puzzles will offer multiple solutions, encouraging players to experiment with their inventory and environment.
Befriend the most unexpected and peculiar of companions throughout Daventry!

Future chapters can be downloaded from in-game upon individual release throughout 2015 and 2016.

Downloads-only for now, but hopefully this'll get a physical release at some point. As usual these days, the best bet for getting physical copies of PC games is... importing them from Europe!
