September 16 Update Notes

* Marine Eco Package 1 — DLC Update

Marine Eco Package 1 has been reworked: instead of adding a few new fish species, the DLC now brings the seafloor itself to life.

New ecosystem creatures appear while the terrain is generated: seahorse (above 3000 m), deep triangle fish (below 3000 m), sea urchin, feather star, yeti crab, and the ambush-hunting bobbit worm.
New decorations that match the terrain: three shades of seaweed, corals that follow the colour of the coral tiles beneath them, and scattered shells and starfish.
Collectibles: sea urchins and shells/starfish are picked up on contact — sea urchin +500 fish coins, shells +100 fish coins.
The bobbit worm cannot be captured, but it can be killed with the harpoon, dropping fish coins and Enhancement Alloy.
Deterministic placement: decoration is seeded by the map, so the same dive always grows the same ecosystem.

* Leaderboard UI

The top three ranks now show a laurel medal badge.
The rank cells for the top three are taller and wider, so the badge is no longer clipped, and a bug where a rank cell could collapse to zero height is fixed.

* A Note on What's Next

My main effort is moving to a new game. Deep Drift Signal Below stays online and playable, but from now on it will receive minimal maintenance only — critical fixes and keeping the game running, with no new content or features.
Bug reports, balance feedback and suggestions are still very welcome. Please post them in the community hub / community discussions, where I can read them all in one place; replies and fixes may take longer than before.
