Gravity Loop

Move with the arrow keys or A/D. Press space to invert gravity (your character now falls upward). Press space again to invert back. Reach the goal to complete each level. Some levels include collectibles for completionists; the main goal is reaching the exit alive.

Gravity Loop builds an entire game around a single mechanic, which is risky design but executed with care. The mechanic itself — press a button, gravity inverts — is simple enough to explain in a sentence and intuitive enough to grasp in the first level. What makes the game work is the disciplined level design.

The 60 levels are organised into three tiers of 20. The first tier teaches the core grammar: how flipping interacts with horizontal momentum, how to stack flips to clear longer gaps. The second introduces moving platforms whose direction depends on which side is down and switches that require timing two flips precisely. The third combines all earlier elements into multi-flip choreographies that occasionally require eight or nine sequential gravity inversions to complete.

The physics engine is precise and predictable. Jump arcs are deterministic; flip transitions are instantaneous; collision detection is generous on edges in the player's favour. The game feels fair, which is essential for a puzzle-platformer.

The mobile implementation is the game's weakest aspect. Touch controls require an on-screen flip button that sometimes occludes important parts of the level. The game is genuinely better on a desktop with keyboard controls. For 60 levels of focused, well-designed puzzle-platforming, Gravity Loop is a strong recommendation.
