Cool game! It took a long time to get a hang of it, and I wish that there was a multi-select feature so that I could move my civilian ships all together.
The fact that my ships didn't move the amount that I told them to each turn really messed me up. :( I would plug in a long movement, and the ship would get stuck halfway along its path, and then die.
I'd also like to echo the other players who say that it was really hard, and hard to learn - I ended up dying on the first level, within a few turns, and had no idea what I was doing wrong. After reading the comments, I realized that you could use batteries and shoot (Somehow I missed this, even after reading the How To Play menu) and gave it another try.
On my second playthrough, I basically sat in the spawn to start, and knocked off the enemies as they came to me, up until waves started appearing behind me that I could not aim towards, which felt very unfair. I understand that you probably didn't want players sitting and killing off all the enemies before moving forward, but there should be a better way to disincentive that than spawning enemies which you can't aim at.
Despite my grips, it's honestly a really neat game! I think that this could be polished up into something really cool, after the jam is done!
