Terminal TD

A tower defense game that runs entirely in the terminal. Place towers, survive the waves, keep the base alive. Installable with Homebrew, or as a binary for macOS, Linux and Windows.

Written in Go on tcell. Enemies route to the base along a flow field, so walls and new paths change where they walk. Maps and waves are plain JSON.

It ships an MCP server, so an agent can play level designer: read the rules, author a map and its waves, validate that every spawn can reach the base, and simulate a run to see whether it's beatable, before you ever play it.
