## Parent #90 ## What to build Deliver responsive deterministic Snake with progression, difficulty, touch, pause/restart, feedback, and one evidence-based social context. ## Acceptance criteria - [ ] A predictable multi-turn buffer and fair collision rules are pure/seeded and tested. - [ ] Levels/difficulty, score, pause, focus loss, restart, touch/swipe, and clear game over work. - [ ] Sound/visual feedback and reduced motion feel responsive without changing deterministic rules. - [ ] One bounded spectator/friendly-round/shared-session presentation is evaluated and only shipped without an unjustified multiplayer rewrite. - [ ] Behaviour is built in vertical red → green cycles through public interfaces where implementation changes are required. - [ ] An independent reviewer gives READY and all required GitHub CI is green. - [ ] Deployment-sensitive behavior is verified on production after merge. ## Blocked by - #100 — PRD 25.10 - #107 — PRD 25.17 - #108 — PRD 25.18 - #109 — PRD 25.19 ## Specification [PRD 25](https://github.com/Anuraj-dev/2d-metaverse/blob/main/docs/specs/25-pilot-delivery.md)
