Ideally you want to build upwards as quick as you can and cut off the slimes where they spawn, barring that you can try and build up some resources under an overhang where nothing but slime balloons can reach.
As for how to escape, exploration is the key. You need to find and talk to both of your crew mates, who are located in opposite corners of the cave.
I get that, and have already set up a decent energy supply. But even with maxed out buildings and EVERYTHING put into defenses they still decimate it.
And with escape, I have already spoken to both of them, but it says "I can't leave them behind" or something, even when I power the teleporter on.
Thanks for replying by the way!
That's fair.
Oh, I also found another issue while playing through the second area too.
I figured out a "workaround" of sorts to get resources without being bothered by the slimes, by only building in the higher sections so the slimes couldn't reach me.
As a result however, they just piled up on the ground floor beneath my buildings, and it rapidly caused my game to lag really heavily.
