The game touts itself as "the #1 operating system for daily tasks such as skeleton smashing and loot-organizing," with a user interface similar to that of Windows 98. The player arrives on the island of Kingsway, a randomly generated island, in hopes of fulfilling The Prophecy to destroy The Sky Eater. To gain the power necessary to have a chance to succeed, the player must delve deep through dungeons, explore caves, and complete quests, while destroying the hordes of monsters in their path... Or die trying.
Kingsway has examples of:
- Crapsack World: Monsters and running everywhere. Cultist are summoning demons. The church is worshipping The Sky Eater and raising undead. And people are scamming people through fake quest mails.
- Genre Throwback: To 90's Windows graphical roguelikes such as Castle of the Winds.
- Macro Game: Each time you finish a game (Wherever by dying or succeeding) you earn gems to unlock stuff in the Gem store, which includes more starting perk options, more customization themes, and unlocking window shortcut keys.
