Is there any option to disable Ghosts in the game, I don't understand full why they spawn but sometimes in a game I end up with several clusters of ghosts that don't seem to get killed and also can't be destroyed by selecting boom, it would be cool if there was an option to disable them

Ghosts are spawned from the Imperial Tomb artifact. They randomly seek out ships and destroy them.

That was an interesting bug to make "BOOM" not work, but that will be fixed in the next update :)

I don't really want to add an option specifically to disable them, but maybe there should be a mechanism that eventually takes them out ... Just need to think of something that makes sense :)

I would really enjoy an option to disable artifacts. If I play without transcendence or degeneration the map eventually lags up with 1000 ghosts

Yeah I need a way to reduce the ghost count

Update on this: Ghosts are capped at 6 per artifact, and they will be more active in adventuring out to attack other ships, as of the next major update.

Awesome! good to hear
