Devlog: week 12 of a fishing game built with Claude Opus 5.5
Reddit user RUSuper posted week 12 of a personal devlog in r/ClaudeAI for a fishing and exploration game, describing a new exploration mechanic: players find an exploration icon near certain locations, approach it and press the action button to receive an item, note or quest progress after a few seconds. The update also adds a 3D "Cabinet" scene for collections including Island Dioramas and Ship in the bottle items, each ship carrying a story tied to a real historical, mythical or in-game vessel, plus World of Warcraft-style achievements with no gameplay benefit. The developer describes keeping a Decisions.md file where user decisions override AI ones, running separate sessions at different effort levels and relying mainly on Opus 5.5 alongside OpenAI image generation, ElevenLabs sound effects, TripoAI models and Blender MCP, with listed project costs totaling roughly $850–900.
The post documents one solo developer's multi-tool, cost-accounted workflow around Opus 5.5, offering a concrete example of AI-assisted game production.
