Hi, I'm so happy that you are enjoying the game. Sorry you are running into issues with this old build. It was later discovered that the spider drop ships cause massive framerate drops when many of them start appearing. I won't go into details why this happened but lets just say the game could drop from 500fps to 20fps. It was an easy fix once it was discovered and is gone from the full game that is appearing next week.
Thanks for being into us people, but it's really just me. I'm a solo dev. :D
Looking forward to seeing you over on the game's Steam forums. http://steamcommunity.com/app/780390/discussions/
