Thank you very much! You're correct in your guess that the wind was made with my voice. I recorded it by blowing straight into my mic multiple times, removing any excess sound, layering and rearranging them to sound more natural, and then finally importing them into unity where I would add a reverb effect. You are the second one to guess that :P
In regards to the extra content, I actually have some elements of the search light detection system implemented but I was unable to get it to work properly before the game jam came to an end so I disabled it upon release. What would happen is that the alien ship would detect the player and start tracking them. The lights would actually turn red and an alarm would blare from the ship. The main problem in the end was trying to figure out if the player was in an area that the ship shouldn't be able to see in to. It was buggy and didn't work most of the time.
I might get around to giving it an update soon, just not now (unless there's a major bug) since I practically burned myself out of working on that game over the course of the week. I'll try to remember to let you know if I do :)
