Dual Surface Shift

Dual Surface Shift is a smooth sci-fi runner built around gravity switching and clean level design.
Your character runs automatically through a futuristic industrial world.
With a single tap, you flip gravity, fly between the floor and the ceiling, and continue running on the opposite surface.
Each level has one clear goal:
reach the end of the distance.
Along the way, you can collect coins and bonuses for extra progress and achievements — but nothing is mandatory.
Miss a collectible, and you can still finish the level.
The game is carefully balanced:
• obstacles are spaced fairly
• swaps are always safe and readable
• success depends on timing, not luck
Achievements are designed to be approachable and rewarding, encouraging experimentation rather than perfection.
