This RNG result will probably be deadly to new players.

It took me a few seconds but then I realized that I can just move the airlock one tile up, no problem.

Might be best to ensure the starting screen doesn't include impassible tiles.

Ah, yeah - that can happen. I had a system a while back to remove any rocks etc from around your starting base, but that also had bugs. Like you said, you can just move the airlock, but it's not obvious to new players. Will try and get that fixed sometime soon. Thanks!
