There is a little bit of sand inside the building that I always put the cube on that angled it down a bit. I did this every time apparently and only noticed the issue when I did a final playthrough just before submitting. That is probably one of the biggest errors and I completely missed it until right before the deadline when I didn't have time to fix it.
If anyone runs into this issue I apologize and the best I can do right now is suggest you use the sand inside the small building to angle the laser down a bit.
