Build a Side-Scroller Game

Infiltration side-scroller platformer (precise, Mario-like). Canonical game: Rothulk. Machine-readable companion: blueprint.json (read by the Build Plan engine to match genre + order the MVP worklist).

Required asset classes (★ = MVP)

• ★ Sprites — hero (idle/run/jump/hurt), 3 enemies (blood-blob/spitter/charger), projectiles, static + moving platforms, acid/spike hazards, embers.
• ★ UI — lives (x3), HP bar, objective text, progress bar, ember counter. Later: title, level-complete, game-over.
• ★ VFX — stomp pop, acid splash, hit flash.
• ★ Music/SFX — gameplay loop + jump/stomp/hurt/ember SFX. Later: escape-phase theme.

MVP slice

Hero physics (jump/land/coyote) → static AABB + moving-platform carry collision → 3 enemies (patrol/lobber/dash) → stomp-kill → acid/spike hazards → phases (infiltrate → core ignition → escape) → 2 levels → HUD (lives, HP, objective, progress, embers).
