Hey Cool game!
I like the idea you have here - ship building games are always fun. I got to about the third stage where there was several of the smaller ships, and I wasn't able to select the furthest one as a target. I'm not really sure why - is it a bug? The main thing to work on I think is communicating that to the player. Just adding some clear indication of how to play the game, ideally without having to read the description, would really clear things up.
Apart from that I actually liked your game, you don't see that many strategy games created in jams, and I think your system has potential if you want to keep working on it in the future. If you have some time, come and check out our game too!
