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. 

Sorry you got stuck! If you get stuck in an area again can you post a screenshot of the area? 

Generally the path to the exit of each level isn't gated too heavily, but you might not have picked up some of the mechanics to progress through the landmark area or out of an arena. If you were stuck in the swamp I'm guessing a geyser or swamp bubble was somewhere nearby. If you see a swamp bubble just stand on it to float upwards and to use a geyser just stand on it until it blows you upwards.
