Hey! First off, just wanted to say thanks for the description of what you did/did not have time for, it was really helpful context for how to judge the game. We also spent most of our time on art and systems and didn't have much time for the content.
But man, your systems look goooooood. The game looks, sounds, and feels great. The turrets shoot intelligently, no bugs to speak of (at least that I noticed). That's a really strong foundation for additional work, if you choose to keep going on it. I hope you're very proud of yourself.
