type-two d0caf983a0 Initial commit: MRPGI — Apple-Silicon AGI adventure engine
A new-school reimagining of Sierra's 1980s AGI interpreter in Rust + macroquad:

- Dual-buffer (visual + priority) room model with hand-painted walkability
- In-engine room editor: brush/line/rect/fill/pick/erase/oval/image/spawn/object tools
- Sprite pipeline (PNG -> EGA quantize), multi-room worlds with edge exits
- Objects with look/use/needs/keys/win conditions (no code)
- Forgiving text parser + optional local-LLM lane (Ollama / OpenRouter)
- Branching NPC dialogue trees, chiptune SFX, per-room ambient music
- Content kit: 61 archetypes across fantasy/scifi/monsters/saucy/horror
- Full docs: README, EDITOR_GUIDE, MANUAL, art manifesto + Gemini prompts

Sci-fi sprites — Gemini Nano Banana prompts

How to use: generate each on a solid flat magenta (#FF00FF) background, save the PNG, then key the magenta to transparent (magic-wand / "remove background" in any editor), and drop it into sprites/ with the filename shown. Press R in the editor. (Or just hand-draw in Aseprite — image models are rough at tiny pixels.) The engine snaps colours to EGA on load, so don't sweat exact palette.

STYLE (prepend to every prompt):

16-colour EGA pixel-art sprite, single object centred and standing on the bottom edge, bold readable silhouette, flat hard-edged colours, retro 1980s Sierra/AGI look, cool steel greys with cyan and teal neon accents, on a solid flat magenta (#FF00FF) background, NO text, NO drop shadow, NO scene — just the object.

filename size subject
blaster 16×10 a chunky retro plasma pistol, glowing cyan vent
console 26×22 a slanted control console, blinking cyan keys and a small screen
terminal 20×24 a wall computer terminal, green-on-black screen
