Sub Terra Draconis is now available for Linux. This has been tested on Ubuntu 22, and it will most likely run on any recent or semi-recent distro that supports the Allegro library.

In addition, the game is now available in German and Spanish, thanks to the efforts of Brendan Ferreri-Hanberry and Jorge Carrión Mena. 

Furthermore, this long-overdue patch includes bugfixes as follows,

• Added voice narration for the story screens.
• Added extra pre-level info scenes, help text for centering screen.
• Fixed file interactions in level editor and Steam workshop.
• Fixed bug ending on the wrong map screen, and adding hotkeys for map switching.
• Fixed game hanging after incorrect keypress.
• Fixed accented letters in German.
• Fixed achievements for solving/mastering map and cumulative gems.
• Fixed doors or keys showing incorrect color, dragonfly having empty hint text, hint shown while paused.
• Fixed scrolling speed, duplicate key mappings, path opening in the Dwarven Caves.
• Fixed graphics glitch for forest levels, reversing gravity, and bottom of tall levels (e.g. Waterfall).
• Adjusted gem quota in Falling Up and Down, Little Creatures.
• Expanded hint text in Bye Bye Buddy, What Would Brian Boitano Do, Pipe Dreams.

Finally, the editor now includes control buttons that the dragon can use to move the golems around.
