Abyssal: a Godot engine for DEEP using the player's JAR

Abyssal reimplements the mobile game DEEP in a Godot engine for desktop, browser and Android. It converts a player-provided MIDlet JAR locally, decoding resources and evaluating selected class-file data tables to supply the engine. The implementation covers submarine piloting, stations, trading, missions and combat.
