Well i wanted to try and do something different from all the other puzzle's.I also wanted the first two puzzles to gear the player for the last. So its kind of like "Hey this is what you have todo to solve it" kind of thing.

Thank you for playing!

I like the second two thirds of this, the first part feels unloved. (not to mention it's a little confusing with buttons that seem to do nothing (behind the laser grid) and a button to turn off a lasergrid you can just portal around)

The final bit is the bit that shines, the middle section is OK too but I prefer chambers that work cohesively as one unit, this is broken disjointedly into three.
