Trench Dive

Trench Dive is a game about one resource: time under water. Every mechanic feeds into that central tension. Pearls pull you deeper, where oxygen depletes faster. Bubbles refill air, but they spawn at unpredictable positions. Mines cluster around the richest pearl lines, because otherwise the game would reward depth with no cost. The design rule we kept returning to: any move that makes scoring easier should also make surviving harder.

Oxygen depletion rate was the hardest single number to tune. Too fast and the game was over before players learned the rhythm; too slow and there was no pressure. The current rate scales mildly with depth, which sounds simple but produces an organic difficulty curve — the first 30 seconds feel relaxed, the next 30 feel tight, and by minute two most players are visibly tense. Runs end at 45 seconds and runs push past two minutes; both feel earned.

The visuals went through a full overhaul late in development. Early builds had a flat, dark blue background that made depth visually uninteresting. The current bioluminescent coloring shifts subtly as you descend, so the trench literally gets darker and more alien the deeper you go. The horizon cues are purely aesthetic, but they make the risk-reward narrative feel stronger. Trench Dive shares DNA with risk-first score attackers like Orbit Rush.
