Oxygen Gas

Deep beneath the ocean, your oxygen reactor is the only thing keeping the station alive. It is split into two chambers by a sliding membrane, and the pressure on both sides never stays still.

Drag the glowing membrane up and down to reshape each chamber. Smaller volume means higher pressure, so every move changes both gauges at once. Keep both needles inside the green zone while the reactor throws chaos at you: O2 surges that flood a chamber with fresh molecules, pressure leaks that vent them away, heat waves that agitate the gas and cold snaps that slow it down.

Tap a chamber to fire a scatter pulse and buy yourself a moment of control. If either gauge sits outside the green zone for too long, stress builds toward a reactor breach. Emergency shields can auto-stabilize the system once things go critical.

Earn coins for every second you survive, then upgrade your reactor in the shop: widen the safe zone, dampen surges and leaks, or stack extra shield charges for longer runs.

Easy to learn, tense to master. How long can you keep the oxygen flowing?
