ExVector: Engineering a Metroidvania Extraction Shooter (the Xtractvania)
Combining non-linear Metroidvania progression with PvPvE extraction creates an immediate soft-lock hazard whenever rival operatives seal corridors behind upgrade-gated bulkheads. In ExVector, up to sixteen operatives and autonomous security drones enter seeded twelve-to-sixteen sector graphs validated for at least three structural loops and breadth-first safe spawn routing. We walk through how the rapid-fire blaster and charge beam unlock colored hatches, how our 180-millisecond Phase Dash Parry triggers 60-millisecond hit-stop reflection, how capsule traversal and analog IonTether momentum feel responsive, and how overlapping thirty-minute raid epochs prevent dead queues across browser sessions before the Sector Purge.

Live two-phase Smart Engine synthesis gave The Everything Quiz accurate custom trivia rounds, yet also imposed a fifteen-second generation delay and per-session API cost that exceeded ad revenue economics. Rather than stalling multiplayer lobbies during every topic request, Crenet Games migrated question persistence to Supabase PostgreSQL and embedded 11,050 existing prompts with 768-dimensional multilingual vectors. By routing incoming player topics through IVFFlat cosine similarity at a tuned 0.40 threshold, median lookup latency fell from fifteen seconds to 297 milliseconds while offline batch workers backfill sparse subjects seamlessly, preserving smooth host and mobile room pacing without continuous token spend.
Read Technical Deep Dive →Bulletproof Payment Webhooks
Relying solely on public Stripe webhooks risks dropped player purchases whenever serverless cold starts or transient downstream timeouts delay fulfillment. To guarantee Sparks delivery without exposing internal game backends, Crenet Games isolated webhook ingestion behind an Express perimeter service that validates raw cryptographic Stripe signatures, persists idempotent PENDING locks in Firestore keyed by session ID, and forwards sanitized payloads over a private VPC using stateless RS256-signed JWTs. A twice-daily Cloud Run reconciliation engine with five-minute claim locks retries pending records and sweeps trailing twenty-four-hour Stripe events so zero transactions are lost.
