Reef Sweep

Playable demo · Full game in development

You’re playing an early demo of Reef Sweep. The full game is in development, with release timing to be announced.

Play the demo here on Wavedash.

In the current playable demo
Dive into Lantern Bay, hunt invasive lionfish and give the reef room to recover. Explore coral gardens, a sunken wreck and an old outfall, then bring your catch home and put your earnings towards better diving gear.

Explore Lantern Bay
Start in the warm shallows of Sunlit Gardens, then follow Tideglass Passage’s sheltered nursery route across the tide race to Cathedral arch. Further out, Mangrove Reach has root channels and a bright sandbar, Azure Cenote opens into deep limestone basins, and Rusted Harbour shelters fish among wreck ribs and old cargo containers. Seaweed sways with the current, your regulator keeps you breathing, and bubbles rise towards the surface. Swim up for a look at the coast, though surfacing won't refill your tank.

Hunt lionfish and restore the reef
Get close, settle your aim, hold to draw the pole spear and release to strike. Hold Interact to secure the fish in your collection tube before moving on. Lionfish spines hurt and drain your air, so give them room. Between hunts, clear abandoned fishing gear, plant nursery-grown coral and build your conservation reputation. After earning eight reputation, meet the university research team to take on a funded field survey. Take on restaurant orders and conservation contracts, and return to a reef that remembers your work. Fish return between dives as you keep clearing lionfish. Come back for three, four or five productive outings and the reef starts to bustle with larger, more colourful schools.

A reason to come back
Take on achievable contracts and see your progress during the dive. Every third game day brings a local Sweep event with its own objective and score. Publish wildlife and cleanup highlights to build an audience and earn recognition. On later outings, listen for boats overhead and keep clear of active fishing lines; abandoned gear can be recovered once the boat has gone.

Better gear and night dives
Spend your earnings on fins, a better spear, more air and a battery-powered scooter. Nine equipment types have five upgrade levels each, giving you more room to explore as your diving business grows. Later equipment service gets cheaper as you gain field experience. The scooter’s motor rises with your thrust and quietens when you stow it. Upgrade your regulator to level 2. Head torches become available on game day 4 with six conservation reputation; fit one and unlock Tideglass Passage to try a night dive. Keep an eye out for the reef shark. High graphics adds shadows across the reef, including those cast by your torch; reload when prompted to apply the full detail.

Check your dive watch
Raise your wrist to check air, depth, dive time, secured catch, battery and the air you need to get home. Press V, tap Watch or use your mapped controller button. Keep the usual air and timer display, or turn it off in Settings once you're comfortable using the watch.

Prepare your catch
Back at the harbour, try the optional filleting activity. Time three careful cuts, see your grade and check the exact bonus before you sell. Careful preparation adds up to 30% to the value of fish sold. You can skip it and go straight to deciding what to sell, donate or serve as meals.

Play your way
Use WASD and the mouse on desktop, or swim with the touch stick and drag the scene to look around. On touch, hold and drag Draw to aim, then release to strike. Portrait and landscape layouts are available. Controllers are supported too, with a USB Backbone preset and a calibration guide in Settings if your buttons or sticks need remapping. When mouse capture is unavailable, you can still look around by moving the mouse over the game.

Music that follows the dive
The original score, “Room for Life,” uses sounds adapted from Pocket Chordsmith. Its layers change with the dive, wildlife and danger.

Planned for the full game
The full campaign is in development, with plans to start a new life in Lantern Bay and meet its residents. This planned content is separate from the current playable demo. Release timing will be announced.
