Браузерная 3D-игра в аквариуме: жёлтая подлодка среди золотых рыбок и кораллов

Build a one-file browser 3D game set inside a glass aquarium tank. The player pilots a small round yellow submarine pod along a sandy floor dotted with smooth grey rocks, pink and purple corals, orange sea fans and swaying green kelp. Shoals of stylised goldfish and small coloured fish swim around and react to the pod. Use a calm teal-blue palette with light shafts from above, a rippling water surface seen from below and soft depth fog. Add a minimal HUD with a score counter, a distance readout, health or energy bars and a level title card reading Sunlit Shoals that fades in and out. Controls: keyboard to steer and move the pod, with a smooth chase camera. Give the pod a small interaction with the fish, such as scooping or scaring them, that raises the score. Model every object from simple procedural geometry so the game runs smoothly in the browser. Done means the scene loads instantly and can be played for several minutes.
