Angry Baseball

memoryTechnical Depth 7/10

Real math where it matters: the pitch release solves initial velocity analytically compensating gravity and the breaking-ball's constant acceleration together, so curves still cross the strike zone precisely (game.js:229-239). Batting skips rigid-body bat collision for a tunable two-axis model — timing (early=pull, late=push) × aim (under the ball = fly) — blended into an impulse for cannon-es. Simplified per-tick Magnus force; every texture is procedural canvas (turf stripes, ball seams, sky). No shaders or post-processing; the hard physics problems are deliberately routed around.

stadia_controllerGame Design 7.5/10

The 'every pitch must pay off' juice philosophy fully executed: a shrinking timing ring that snaps green in the zone, a PERFECT metallic ring whose synthesis varies continuously with quality, combo pitch ladders, crowd volume scaling with distance, and full-screen record-break text. Intermittent reinforcement by design (golden balls on pitches 5 and 9, a bomb ball that rewards *not* swinging, a 4% chicken pitch, a JACKPOT pig crossing the outfield) — PLAN.md literally cites it as the addiction mechanism. Nine bats with real feel differences. Docked for inheriting most systems 90-100% from angry-pig.

securityBackend & Security 6.5/10

The most defense-aware backend of the five: per-mode plausibility caps (distance board 400 m; survival estimated from the note field which is itself capped to prevent bypass), an audit log, and an in-game read-only admin dashboard where the rate-limit hits column doubles as an attack signal. The staggered-submit fix (two boards hitting the same 3 s IP limit → frontend delays the second by 3.5 s) shows self-debugging, though it patches the backend with a client hack. Same family sins: the '0501' admin password sits in a test file, and names are identities.

codeCode Quality 7/10

Reasonable module boundaries where it counts: batting.js is a zero-dependency pure function ('pure math, no deps' says its header), fx.js uses dependency injection to break circular imports, dispose discipline is complete. But game.js is a 1,781-line everything-file — state machine, UI wiring, shop, leaderboard client, admin client, touch stick — contradicting PLAN.md's own module plan.

experimentTesting 3/10

The only project in the series with tests at all: 8 puppeteer-core E2E scripts, including a bot that actually plays baseball — polling a debug hook for the ball's z-position and clicking the swing at the right moment, completing full 10-pitch games. But none of them assert anything (console.log for eyeball judgment), there is no CI, the Chrome path is hardcoded to Windows, and the perfectly testable batting.js pure function has zero unit tests. Verification scripts for an AI workflow, not a regression suite.

verifiedCompleteness 8/10

A professional-grade delivery for ~a week: 4 modes, 12 challenges, a 9-bat shop, 4 leaderboards, threaded message board, admin dashboard, 7-day peak chart, mobile stick, settings, onboarding, opening camera sweep — deployed with a marketing page and YouTube embed, fully playable offline. Docked for documentation drift: the README still advertises the slow-motion ball-cam that a commit explicitly removed.

emoji_objectsOriginality 6.5/10

Home-run derby games are plentiful; putting destructible physics targets in the outfield is not. Bomb balls that reward restraint, a pitcher who throws chickens, a joke salted-fish bat — the comedy toolkit builds a personality. Still the fifth work in its own universe, on its predecessor's engine, with a rhythm-game timing core: clever recombination rather than invention.
