🎮 Game Overview

An arcade-inspired progression game built on HTML5 Canvas + JavaScript. Collect Alpha and Omega pickups to fill the level meter. The balance between Alpha and Omega decides which perk you unlock (25 possible outcomes).

⚙️ Core Gameplay

Pickups Alpha + Omega drop randomly. Missed pickups transform into Heart pickups (heals 1). Hearts always spawn (even at full health), last 10s.

Health Start with 3 hearts. Lose 1 on enemy hit or collision.

Upgrades (25 total) Determined by Alpha/Omega ratio. Middle ranges give common boosts (speed, magnet, shields). Extremes unlock rare perks (fire/frost trails, piercing shots, cosmetic glow).

Progression Pickups required increase on a smooth curve (12 → 18 → 26 → …). Every 3rd level spawns special events for variety.

🛠️ Tech Canvas rendering (JavaScript) Web Audio API for sound + effects. JSON data for upgrade mapping.

🚧 Current Phases Phase 1: Survival shooter (ship dodges + collects). - Main Game Phase 2 (WIP): Runner with hazards, pickups, momentum speed. Phase 2 (WIP): Classic Breakout. Phase 2 (WIP): Don’t stand i “fire” mode.

🔜 Planned Phases

Circular Breakout (Y-paddle inside a ring). Snake (body color = Alpha/Omega ratio). Pac-Maze (collect, dodge, escape). Frogger-Crossing (hazard lanes). Match-3 inspired (simple align mechanics).

🐛 Known Issues

Some perks need visual polish (glow, trails). Pickup bias sometimes skews too often mid-range.

📌 Next Steps Complete current phases. Continue perk balancing + FX polish. Add planned phases
