RPG Starter Kit is a complete little adventure in the spirit of the classic 8-bit top-down quests: a 48-screen overworld (grassland, forest, desert, graveyard, mountains), nine caves, three dungeons with keys, locked doors, shutter rooms, push-block puzzles, bombable walls, maps and compasses, three bosses and a final showdown. The hero wields a sword and a set of B items (boomerang, bombs, bow, candle, potions) and grows stronger with heart containers. One developer config and two presets, Retro and Modern, control every convenience: grid vs free movement, autosave, respawn rules, map fog and hints, the NES colour palette and chiptune vs orchestral music.

Players get a full Options menu with rebinding for keyboard and gamepad. Steam features (achievements, stats, leaderboards, cloud save, rich presence, Deck support) go through the optional GodotSteam addon and do nothing without it. Everything is CC0 with documented sources: the default art is the CC0 Ninja Adventure pack, music by Juhani Junkala and Ninja Adventure, plus original additions made by scripts in tools/.

An alternate AI-generated art set can be switched on from Options. Levels are text files generated and validated by scripts, and a scripted smoke test plays the real game (96 checks).
