A tropical island has a pier, a reef and open water, where you can fish from the shore or take your own boat out. Hold the mouse button to wind up a cast, wait for the bobber to go under, then keep the line tension in the green while the fish fights. Where and when you fish decides which of the 18 species bite. Joe's stand buys the catch, and Marta's chandlery sells better rods, reels and boat parts. It needs a recent browser with WebGPU and a capable graphics card, and the first load can take a minute or two.
How the creator made it
The creator made a coastal demo with Claude Opus 5.5 and multiple agents, mostly giving them short requests for additions or visual fixes. They say the demo took about eight hours in real time. They then turned it into a fishing game, adding wear to the scenery and moving to native WebGPU to give the AI more control over rendering. The creator says one optimization pass raised frame rates from 60 to 100 frames per second, though later features used up most of that gain.
