Add pixel-art assets and a graphical (pygame) version of the game

[m5136771]

What this adds

A cohesive set of pixel-art sprites and a new graphical, point-and-click version of Liar's Dice that actually uses them. The original terminal game (liars_dice.py) is unchanged — this is a second way to play.

New files

• generate_assets.py — builds every sprite with Pillow. Each sprite is authored at a tiny native resolution (a grid of characters) and upscaled with nearest-neighbour for a crisp, chunky pixel look. Produces: six dice faces, a "hidden" die for the bots' secret rolls, a pirate skull, a treasure chest, a gold coin, a dice cup, and a wooden plank used to tile the table-top.
• assets/ — the generated PNGs, committed so the game runs out-of-the-box with only pygame (no Pillow needed just to play).
• liars_dice_gui.py — a pygame UI on a wood table: skull/cup avatars, face-up player dice, hidden bot dice, a current-bid banner, a value + quantity bid picker, RAISE / CHALLENGE buttons, a dice reveal, and win/lose screens. It reuses the same bot strategy as the terminal version.
• requirements.txt — pygame + pillow.

Changed

• README.md — documents both versions and the artwork.
• liars_dice.py — one comment line: marks the "Add a GUI" future-feature as done. No behaviour change.

How to play it

pip install -r requirements.txt
python liars_dice_gui.py          # artwork is already in assets/
python generate_assets.py         # only if you want to re-create the art

Testing done

• Ran generate_assets.py and visually reviewed every sprite.
• Headlessly rendered the human-turn, reveal, and win/lose frames to verify layout.
• Simulated 200 full games to completion (turn order, challenges, eliminations, win/lose) with no crashes.
• Drove real button clicks through handle_click (ROLL → bid → CHALLENGE → reveal → CONTINUE → PLAY AGAIN).
• Byte-compiled all modules.

Preview

The graphical version on a human's turn (six-die value picker with quantity stepper and RAISE/CHALLENGE buttons):

Bots across the top hold hidden dice; your dice are face-up; the centre banner shows the standing bid and total dice in play.
