Revisited the game this weekend. I got slightly better at it, and the genome sequencing stuff makes a bit more sense to me now as to how to use it -- hope the full release has a proper tutorial for it. :)
In the 2nd area, once I get to the sort of eastern side of the map, I just can't grasp how to progress further. I over-rolled trying to drop down to some elevated area (don't see any way back to it). Eventually the walkway to the starting area in the east crumbles away, and I don't see a way to return to it. Other blocked areas there require a keycard or detonator to progress, and I don't have either.
I suspect once the game releases, some smarter player will have a Steam game guide to get through this, but just thought I'd ask now. :) Although i realize with the procedural generation, there may no walkthrough to speak of.
