Takara Sea — An HTML5 Underwater Treasure Hunt Game

A simple but challenging underwater arcade game. Now available on the Codoh Game Portal.

You control a submarine, dive into the sea, collect treasure chests, and try to make it back alive — while avoiding dangerous sea creatures.

It’s a small project, but I focused on:

• fast gameplay (new browser tab and play)

• clear mechanics

• replayable challenge

No installation required — just open a new browser tab and play.

It’s built with HTML5 and JavaScript. The full source code is available as a separate purchase for developers who want to study it or build on top of it.

[Note: This game is not supported on mobile browsers. Please play on a PC or laptop for the best experience.]
