Congratulations on making your first game (with Unity at least)! I'd say this is a pretty solid effort for having never used the engine before during a gamejam. I quite liked this ships movement, it felt pretty nice to fly up and down. The parallax background really helped with the atmosphere (as well as most of the visuals and audio in the game, itcreated a very eerie atmosphere).
It would be really awesome if you checked out our game!
