Two AI coding agents, Muse Spark 1.2 and Claude Opus 5, were handed Day of the Tentacle and nothing but structured tool calls to play it with, no mouse, no hints, just commands and whatever came back. Some of those transitions look deliberate; others look like the game simply moved on without asking. Watch the whole run and decide for yourself which was which.
Each agent plays the same game from the same save, at the same time, through the ScummVM MCP server, no pixels, no screen reading, only structured tool calls. One instance per agent, side by side.
Agents in this run:
- muse-spark-1.2 with Pi
- Claude Opus 5 with Claude Code
