This interactive island was built in 8 hours with Opus 5.5

Dan Greenheck utilized Opus 5.5 with simple prompts such as “add X” and “make it better” to construct an interactive island in approximately 8 hours. The project, named TideWater, features diving birds, burrowing crabs, fish alongside a whale, wind effects, and dock lights at night. This endeavor consumed $1,874.40 in tokens, representing 59% of his weekly allowance on a Max (20x) plan.

This report details the token cost and development time for an interactive island built with Opus 5.5, unlike many demonstrations that omit these practical metrics.
