Asteroids Recharged Webapp

How To Play

• Goal: survive, chain kills, and post the highest score.
• Destroy asteroids to score and progress to higher in-run levels.
• Enemy ships appear early, but they start firing only after later progression.
• UFO and Boss enemies spawn over time and are worth higher points.
• Collect powerups (`spread`, `rail`, `shield`, `burst`) to increase damage and control.
• `Arcade` runs until lives reach zero. `Challenge` adds timer and medal thresholds.
• Submit completed runs to earn XP/Credits, unlock cosmetics/abilities, and climb leaderboards.
• Use `Save Checkpoint` and `Load Checkpoint` to resume local in-run progress.

• P1 movement: `A` turn left, `D` turn right, `W` thrust, `S` reverse thrust.
• P1 fire: `Space`.
• P2 co-op movement: `J` turn left, `L` turn right, `I` thrust, `K` reverse thrust.
• P2 fire: `Enter`.
• Rotation + thrust momentum is arcade-style inertia, so tap or feather inputs for control.

• `Score`: points earned this run.
• `Lives`: shared life pool remaining.
• `Lvl`: current wave level.
• `Ast`: asteroids currently alive.
• `Enm`: enemy ships currently alive.
• `Combo`: consecutive hit chain count.
• `Mult`: active score multiplier from combo.
• `Acc`: accuracy = shots hit divided by shots fired.
• `Power`: active power-up type and remaining time.
• Challenge mode adds `Timer`; co-op mode adds `Co-op` tag.
