The editor makes maps; the engine plays them. Both are early alpha builds for Windows; every version stays available here.

Test build

This version was built without the final optimisations, so the game runs slower than a production build will. It is for trying things out, not for measuring.

What changed

First alpha preview: the editor (terrain, objects, Go scripts, imports from Warcraft III, players, shaders) and the engine (play a map, the in-game interface, chat and commands, a map's own interface from Go).
The Go API ships with the editor; maps get a go.work so that gopls completes it in your code editor.
Maps carry a format and the version that saved them; older maps are migrated on open.
Built from the development profile, without the final optimisations: expect lower frame rates than a production build.
