Pretty cool concept. This could be a pretty fun game if you decided to refine and polish it. It certainly displays a higher difficulty level than some games of the same caliber. One of the main things I had an issue with though, was trying to figure out the line of sight for non-laser entities, maybe that was where the difficulty came in.
All in all, I can see you put in a lot of work, and I'd love to see what you could do with more than just 2 weeks.
