Hi, just found this project, quite interested seeing someone properly finish it off this time, and remembering your old works, I'm curious how you manage to. Will wait until finished to see how it is.
The only thing I'd like to comment on was the story in the manual: You really don't need to overcomplicate things. No need for timey-wimey things, Mental and Sam seeing time and all that. Just have that after TSE, Sam is teleported by the remaining Sirians, then SS2 plays out and that's it. At the end Sam kills Mental in the past, then Sam just fades back to his own timeline but now humanity is alive as if Mental never existed and that's it. It's like an old movie that didn't really care about the implications, because it didn't need to.
