Hello everyone!

As we approach the launch of Kingdom's Calling: The Final Gospel, I wanted to share some details regarding the experience on the Steam Deck and Linux.

• I’ve spent the last several months doing extensive, hands-on testing with the Steam Deck to ensure that the "Holy Quest" feels perfect on a handheld. This wasn’t just a simple export; I’ve spent many hours playtesting every swarm and every stage on the Deck to make sure the controls and performance meet the high standards of the handheld community.

  Verified by the Developer

  While the official "Steam Verified" checkmark can take some time to appear, I have personally verified the following:

  • Linux Native: This game runs natively on Linux without the need for Proton. I have tested the build across SteamOS and desktop Linux (Mint) to ensure a stable, high-performance experience for the Linux community.

  • Performance: I have optimized the game to maintain a solid 60 FPS across all stages. Even in the late-game when the screen is packed with high-density swarms, the performance remains smooth and responsive.

  • Controls: Full Controller Support is baked in. The game is pre-configured for the Steam Deck’s layout, and I’ve also verified that it works perfectly with external controllers (Xbox, PlayStation, Switch, etc.) when your Deck is docked or connected via Bluetooth.

  • Readability: I’ve carefully scaled the UI and text specifically for the Deck’s screen. All stats, menus, and dialogue are crisp and easy to read.

  Hardware Calibration

  Because I want the experience to be great on every screen, I’ve included a Brightness slider in the options menu. This allows you to dial in the game's retro pixel art to look exactly how you want it on your specific display.

  Building this game has been a massive solo effort, and I’m incredibly proud of how it runs on the Deck. I can't wait for you to jump in!

  God Bless!
