subway-sparkstorm

Subway Sparkstorm is a mobile-first rail bullet hell where a repair drone weaves through shifting subway lanes, electrical arcs, and train spark surges. Drag anywhere on the tunnel floor: the drone stays above your thumb while magnets snap into range, build shields, and reward daring near-misses.

What you can do

• Dodge shifting rail geometry — safe lanes bend and squeeze as each wave ramps, so you chase the live gap instead of memorizing a static pattern.
• Graze for voltage — skim sparks and third-rail arcs for near-miss combo points without taking hull damage.
• Magnetize pickups — collect polarity magnets to expand the pickup field and charge a grounding shield that can absorb a direct spark.
• Resume instantly — synced-store persists the current run, rail phase, RNG position, pickups, score, lives, and terminal state so closing and reopening restores the same tunnel.

Built on Synced-Store

This game uses Poe synced-store for durable run state and recent records. The renderer is a lightweight 2D canvas loop rather than Three.js, chosen for crisp bullet-hell motion and safe performance inside small mobile Poe iframes.
