I spent a lot of time playing this game and really enjoyed it! A few things that bugged me are the AI buddy taking building space right where you start, since I was a complete noob I didn't expect my AI buddy to just put blueprints everywhere before I could decide how I wanted to build my base, the audio completely disappears when your device goes into sleep mode with the game running, and the miners refine the resources at your allies refinery so there was a point about a hour or two into a save where i just could build anything because i had 2 materials left and the miners kept mining ores and refining them at my ally's refinery instead of my own.
Edit: I love the game and can't wait to see what it is like when it comes out.
