Game Concept: “Reflex Arena”
Genre
Real-time competitive 1v1 / 2v2 skill-based action game
Platform
iOS (iPhone first, iPad optional)
Core Idea
A pure skill game where players compete in short, intense arena matches using precision timing, reflexes, and positioning — no RNG, no pay-to-win.
Each match lasts 60–90 seconds, making it ideal for mobile sessions while supporting competitive depth.
Core Gameplay Loop
Matchmaking
Skill-based MMR
Ranked & unranked queues
Arena Match
Small symmetrical arena
Players control a single character
Objective: score points by outplaying, not overpowering
Score & Progress
Win → rank up
Lose → learn (clear replay & stats)
Cosmetics only progression
Controls (Mobile-First, High Precision)
Left thumb: Movement (virtual joystick)
Right thumb: Aim + action swipe
Tap: Ability activation
Perfect timing windows reward precision (parries, counters)
👉 Designed to feel closer to a fighting game than a casual mobile title.

I am seeking a world-class Systems Engineer / Rust Architect to build a proprietary asset extraction engine on the Solana network. This is not a "Web3 App" or a "DEX UI." This is a purely backend, low-latency machine designed to capture micro-value from market volatility.The system mimics a "digital sluice," using high-precision math to harvest fractional differences that standard rounded-math bots ignore. We are scaling from a prototype to a 30-node distributed network managing 100+ concurrent execution "hands."Core Technical RequirementsLow-Level Rust Mastery: You must be an expert in the Tokio runtime, asynchronous programming, and memory-safe mathematical operations.Solana Network Physics: Deep understanding of the Sealevel runtime, custom WebSocket/Lumen bridges, and avoiding gRPC bottlenecks.Jito & MEV Optimization: Proven experience with Jito Bundles, transaction shredding, and tip-optimization to ensure first-block inclusion.Distributed Orchestration: Ability to architect a master-node system that manages 30+ regional nodes with seamless failover and zero-loss state management.Precision Math: All logic must operate on u64 integers (Lamports) to avoid floating-point rounding errors. We do not "round" to the dollar; we capture the 9th decimal.Key ResponsibilitiesEngine Hardening: Audit and optimize the core Rust logic for 0-latency execution.Node Orchestration: Build the "Master Switch" to deploy, monitor, and update 30 nodes across global regions simultaneously.The "Tax" Logic: Implement a secure, automated "sweeper" protocol that collects fractional value from all child-nodes into a master treasury without interrupting execution.Redundancy: Ensure the system is "Anti-Fragile"—if a validator or node fails, the 50-drop safety protocol must trigger an instant failover.
