I think I found a problem in the level "Dread Not" in Eternal; namely, that the terminal text that sets your objectives er, doesn't; set your objectives I mean.
The terminal I found at the start says you have to set the self-destruct but doesn't mention that you have some circuits to destroy. If I hadn't remembered from a previous test version I might have been stuck in that loop for a very long time; as it was I went around it twice, thinking I was doing it too slowly. Then a memory of the previous version of that level brought the circuits back to mind and I started looking for them.
Are the developers reading this forum? I assume so, and I'll look for a Readme file if not.
