About This Demo

A rolling-block puzzle where your piece is a whole line of cubes. Roll it flat, stand it on end, break it or rejoin it, and turn the camera to

find the way — then land the chain along the goal line to cover it.

It looks simple: tip a line of cubes across a grid until it lands on the goal. Then the level starts taking your line apart — and the real game

shows up. Knowing when to break the chain, where to gather it back, and which way you're facing when you do is the whole thing.

A line that comes apart

Your chain won't roll into empty space, so you can never lose a cube by accident. Drive it into a wall, though, and it shears — the cubes that can't pass break off and wait behind you, ready to rejoin. Reshaping the line is how you fit it through the level.

The angle is a move

Standing and lying, the same chain reaches different squares. And rotating the camera isn't just a look — it turns which way you roll and decides which cubes break away when the line splits. The direction you face is a decision, not a view.

The board fights back

Some blocks don't take passengers: one destroys the cube that lands on it, another warps it into something new, and your line splits at the break. It's never random. When it goes wrong, the trap was always there to see.

Features

• Your piece is a whole line, not one block — the twist everything else is built on.

• Cover the goal line — slot your chain onto the goal line and the level clicks shut.

• Camera rotation that changes the play — it turns your controls and decides which cubes break off.

• Climb and descend — stand tall to go up, reconnect lower to come down.

• Break and rebuild — shear the line against blocks, then gather the pieces back.

• A board full of reactive tiles — destroy and transform your cubes, crumble underfoot, or trigger effects across the level.

• Fully deterministic — no luck, no jank; when you fail, you can see exactly why.

• Full controller support, remappable controls, color themes, and localization.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Syncline is developed by me — AI tools were used to assist with parts of development, including code, some text content (UI copy, tutorial hints, level descriptions, store page copy), localization/translations, and some audio. All such content was directed by me and reviewed/edited before being included. No content is generated by AI at runtime — everything players see, hear, and play is fixed at build time.
