This is a pretty neat game!
Some of the puzzles were a bit easy (Level #8 I believe is mostly just a rehash of an earlier puzzle) but overall these were pretty good puzzles.
One thing I would mention is that the lasers are a bit unclear at times. It's possible to figure out which direction the laser is coming from using the particle at the end, but adding a visible "emitter" at the source would make them more intuitive.
