Delta is a fast-paced space shooter that puts you in the cockpit of a triangular spacecraft navigating through fields of enemies, asteroids, and cosmic hazards. The game captures the raw, mechanical satisfaction of vector-aesthetic arcade shooting — clean geometric visuals, precise directional movement, and satisfying destruction of enemies that break apart into smaller fragments.

The triangular ship design is not merely aesthetic — it determines how you perceive and navigate the combat space. The sharp-pointed nose indicates your firing direction; rotation before firing is fundamental.

Delta's enemies include asteroid fields that fragment into smaller, faster pieces when shot (requiring multiple shots to fully eliminate), enemy fighters that engage you with directed fire, and larger capital ship enemies that present sustained combat challenges. The combination of asteroid hazards and active enemies creates a multi-threat environment where attention division is essential.

Delta combines rotation-based movement with continuous space shooting:

1. Rotate Your Ship — Your triangular spacecraft rotates in place using left/right rotation inputs. The nose direction determines where your shots travel.
2. Thrust Forward — Apply thrust in the direction your nose is pointing. Momentum persists — the ship continues moving in the thrust direction even after you stop thrusting (space physics).
3. Fire Your Weapons — Shoot projectiles in the direction your ship nose is pointing. Hold fire for sustained output.
4. Destroy Asteroids — Large asteroids fragment into medium pieces on hit; medium pieces fragment into small; small pieces are fully destroyed. Complete elimination requires multiple hits.
5. Engage Enemy Ships — Fighter enemies attack with directed fire. Rotate to aim at fighters and eliminate them before they damage you.
6. Avoid Collisions — Contact with asteroids or enemy fire reduces your shield/health. Asteroid fragments fly outward from impacts — stay clear of fragment paths.
7. Wrap-Around Navigation — In most versions, the play area wraps — exiting the right edge appears on the left; exiting the top appears at the bottom. Use this for tactical repositioning.

• Learn the controls before attempting difficult levels.
• Focus on the objective shown at the start of each round.
• Practice early levels to build confident muscle memory.

• Left Arrow / A — rotate ship counter-clockwise
• Right Arrow / D — rotate ship clockwise
• Up Arrow / W — thrust forward (in the direction the nose points)
• Down Arrow / S — reverse thrust (in some versions)
• Spacebar / X — fire primary weapon
• Z / Shift — secondary weapon or shield
• Enter — start / restart

• Left virtual button — rotate counter-clockwise
• Right virtual button — rotate clockwise
• Thrust button — apply forward thrust
• Fire button — shoot

Pro Tip: Rotation-Fire Coordination: - The key mechanic: rotate to face the target, fire, then rotate to thrust direction.

• Delta rewards the mastery of rotation-based movement and momentum management that defines the Asteroids-style genre.
• Momentum Management: - Always know your current momentum direction (where you are drifting, not where you are facing).

• When shooting a large asteroid, be prepared for the fragments. Large asteroids produce 2-3 medium pieces that fly outward. These medium pieces produce 2-3 small pieces each. A single large asteroid can create a 6-9 small-piece hazard field.
• Clear the fragments immediately after creating them. Leaving multiple small, fast fragments unaddressed while focusing on new asteroids creates an overwhelming density of threats.

High-Score Tip: Pacing: - Do not rush into dense asteroid clusters when your momentum is difficult to control.
