Ocean Lining

Ocean Lining is a path puzzle on a compact five-by-five board. In Ocean Lining you trace orthogonal routes between two matching sea terminals for each color, moving one cell at a time along the grid. The aim in Ocean Lining is to recreate the level's reference layout exactly: every cell must match the intended pattern so all routes line up with the solution. That goal turns each stage in Ocean Lining into a small planning exercise as you choose which path to secure before another color needs space.

When you start Ocean Lining you choose easy, medium, or hard. Easier settings in Ocean Lining give longer timers and more lives so you can recover from a bad drag. Medium in Ocean Lining tightens the clock and trims lives a little while keeping the same rules. Hard in Ocean Lining asks for quicker readings of the whole board with shorter time and fewer lives. The rule set in Ocean Lining is identical across tiers, so what you learn on one setting still applies on the others.

During play, Ocean Lining shows score, time left, lives, the current stage index, and a target number on the heads-up display. Score in Ocean Lining counts how many cells already match the reference layout, multiplied by four, so it tracks alignment rather than style points. A round in Ocean Lining ends in success when your filled board equals the puzzle solution; at that moment the score condition in Ocean Lining is satisfied as well, and any remaining seconds add a small time-based bonus to the total shown on the result screen. A round in Ocean Lining ends in defeat if the timer reaches zero or lives drop to zero.

Ocean Lining includes undo to step back through recent commits, and reset to clear all paths on the current stage when you want a fresh attempt on the same puzzle. The board in Ocean Lining scales within the screen while staying square, so tracing paths by touch stays predictable across common phone widths.

Visually, Ocean Lining uses a dark ocean-toned backdrop, neon stroke colors, and sea creature icons at the endpoints. Contrast stays high so separate colors remain easy to read when several paths are on screen. Screens in Ocean Lining are simple text panels suited to a general audience, keeping attention on the puzzle.

Ocean Lining bundles three authored stages per difficulty, for nine layouts in total. After a successful clear in Ocean Lining you advance to the next stage in that tier until the set loops from the beginning. After a failed attempt in Ocean Lining you can retry the same stage without leaving the difficulty you chose. Sessions in Ocean Lining are short loops of choose difficulty, solve, then read the compact victory or defeat summary.
If you like grid path puzzles with clear rules, visible timers, and immediate feedback, Ocean Lining keeps the experience focused from the opening route to the last matched cell.

The flow in Ocean Lining remains the same from menu to results: pick a tier, draw paths between paired sea markers, avoid invalid crossings and wrong terminals, and finish the full grid to match the reference. Returning to Ocean Lining later still feels familiar because each visit is the same straightforward cycle of plan, draw, commit, and review.
