Thanks - I appreciate the feedback. Getting rid of the dropper would take away from a large part of the puzzle, but I'll see what I can do.

really neat map. liked it a lot. I would suggest not having the cube dropper as it can be a little pointlessly annoying when you kill the cube just because you pointed the laser at the cube dropping relay for a split second. I would suggest placeing the second cube in a small glass room that opens up when you tag a specific laser relay. then you simply go and collect the cube. This will make your chamber look nicer as it will be completely rectangular.
My 2 cents.
good job though.
