Chalk & Chance - Evidence-grounded teacher simulation

Current build

Not a chat demo. A rehearsal loop.

The game now includes mission briefing, scenario backdrops, explicit debrief panels, level-up progression, item loadout, local leaderboard, evidence journal, lesson import, and product QA gates.

Mission briefing

Each mission opens with art, story hook, success conditions, reward, evidence edge, and first-move guidance.

Classroom orchestration

Players manage attention, order, composure, proximity, interruptions, and student-specific needs.

Evidence Journal

Live ECD/Elo-style competency estimates show probability, evidence count, uncertainty, and research anchors.

Progression loop

Badges unlock missions, XP grants upgrade points, item rewards change loadout, and runs post to a leaderboard.

Readable debriefs

Encounter, lecture, gym, group, and full-lesson endings show score drivers, next focus, rewards, and replay choices.

Free-text teacher talk

Players can type their own teacher move; the game maps it to the same evidence-bearing action loop.

Lesson import

Paste a lesson plan and generate a playable scenario with objectives, roster, seating, and dialogue hooks.

Research-grounded mechanics

Mechanics trace to teaching constructs

Chalk & Chance is designed as an educational game, so mechanics are tied to constructs and telemetry instead of only to narrative choices.

Productization QA

Verified as a playable product surface, not only a prototype

The repository includes a one-command QA runner that refreshes screenshots and checks the main product gates.

Project load and smoke tests

UI clipping, overlap, button fit, and dialogue padding

Backdrop, item, portrait, and sprite asset quality

Scenario/data integrity and competency-model coverage

Encounter differentiation, lecture mode, gym capstone

Lesson import, telemetry/xAPI, overworld ecology
