How the game travels today
There is no installer yet. The build moves as a folder: unzip, read the note, run Start LOOM. The engine runs beside the client on your machine, your campaigns live in your user directory, and swapping in a newer build leaves them alone.
The build is unsigned, so Windows asks for one extra click of trust on first run. Signing and installers are on the plan, and they need the owner's own certificates.
What your money would fund
A Kickstarter is being prepared, not launched. The engine is ahead of the art, and the campaign funds exactly the gap between here and a beta: the remaining DM portraits, a soundscape for every room, real voices, and the unglamorous work of signing and installers.
It is not live. No amounts on this site are real. The day the campaign opens, this page says so and links it; until then, treat any page that claims otherwise as having drifted from the truth.
