VECTOR

How to play

Program your ship on the timeline, then press play. Destroy every enemy without being destroyed. Each slot is one step of time; after your last action the ship keeps drifting. Clear the puzzle, then try to beat your time (how long it takes) and cost (what your actions add up to).

Keys (left hand)

Q W E turn left / thrust / turn right · A S D fire / shield / ram on-off · F skip a slot · X erase · Space play / pause · [ ] step.

Editing the timeline

• Click a slot, then press a key or click an action. Empty slots just wait.
• Drag across empty slots, Shift+click or Shift+arrows to select. Drag a selection to move it (Ctrl copies).
• Ctrl+C / Ctrl+X / Ctrl+V copy, cut and paste (Ctrl+Shift+V inserts). Right-click or Delete erases.
• Drag along the time numbers to scrub through the run, and scroll to move along the timeline. The orange bar shows when ram is on.

Rules

• Ram is a switch: once on, anything you touch is destroyed, until you switch it off or fire or shield.
• Ships touching without a ram pass through each other.
• Bullets carry your ship's momentum. A shot fired straight at a wall comes straight back at you.
