Gravity Flip Runner

A crisp 60 FPS retro chiptune gravity-inversion action platformer!
Instead of standard jumping, flip gravity polarity whenever touching the
floor or ceiling to fall skyward or downward through neon labyrinth
chambers, thread screen-wrap laser corridors, snatch floating Trinket Orbs,
fire pulse discharges during anomaly battles, and conquer three distinct
Dimension Core Bosses across escalating sci-fi sectors.

FEATURES
- Instant Polarity Flipping: Invert gravity (Space / W / S / Up / Down) on
any floor or ceiling contact to navigate spiked laser vaults, moving
conveyors, and dual-sided screen-wrap corridors.
- Pulse Discharges & Phase Shift Dash: Fire neon pulse bolts (J) to shatter
Warp Patrols and Phase Seekers during anomaly surges, or trigger a short
Phase Shift Dash (K / Shift) for brief invulnerability across laser arcs.
- Trinket Orbs & Checkpoint Beacons: Collect floating golden Trinket Orbs
to boost combo multipliers and activate glowing Checkpoint Beacons to lock
progress inside each multi-chamber sector.
- 3+ Sectors, 3 Core Bosses & 3 Difficulties: Conquer Neon Lab Grid, Warp
Relay Spire, Dimension Core Nexus, and Endless Anomaly Loop across Casual,
Arcade, and Turbo difficulties with 16-bit PCM WAV chiptune audio, JSON
high scores, CSV export, and English / Vietnamese UI switching.
