Add hidden fossils: persistent meta-collectibles - #5
Merged
Conversation
- Fossil entity (src/fossil.ts): bone with warm unearthed glow, bob, sparkle; 30x26 hitbox, re-collectable each run for 150 points. - 3 hidden fossils per hand-built level (9 total), placed on risky ledges, stepping stones and behind the frostpeak gates. - Persistent codex (store.ts tinyrex_fossils): first discovery is recorded by id "levelIdx:i"; re-runs pay score again. - Game wiring: pickup via player collision, first-find status + shake + NEW FOSSIL text, HUD line with bone glyph, menu fossil dots on level cards, lifetime stats line, quest panel row. - Tests: fossil entity/store/level-data integrity + game integration (137 tests total); headless E2E verified.

What
Adds hidden fossils — a persistent exploration reward that turns every hand-built level into a secret hunt.
src/fossil.ts— newFossilentity: a bone with a warm unearthed glow, a heavy bob, a weathering crack and an occasional sparkle. 30×26 hitbox; noupdate()(matches the crystal/heart pickup pattern, animated byt).level-data.tson risky ledges, stepping stones over lava, and behind the Frostpeak gates. Daily levels have none (the field is optional; a-1sentinel keeps ids stable).store.ts(tinyrex_fossils): the first discovery of eachlevelIdx:iid is recorded once and survives across runs; later runs re-collect the same fossil for 150 points again (CFG.score.fossil).game.ts,player.ts,ctx.ts): pickup through the existing player-collision loop; a first-find shows aFossil found! n/9status, aNEW FOSSIL!floating text, a bigger burst and a small shake. The HUD gains aFossils n/9line with a bone glyph; the menu shows per-level fossil dots on the cards, aFOSSILS n/9lifetime-stat, and a new quest row.'fossil'SFX inaudio.ts(unearth thud + warm chime).Why
Gives the game an exploration/replayability hook for almost zero new-engine cost — it reuses the crystal pickup pattern almost verbatim. It also seeds the payoff loop for the upcoming Rex skins (Mint unlocks via fossils).
Validation (local gate — CI is failing for pre-existing unrelated reasons)
