the laser launcher started by it with the laser catcher in the inner part of a passage is unnecessary -- it was .

Too many lasers and pivot cubes make me feel I broke your puzzle. Plus antlines please. Certain cases call for hiding but here, doesn't make sense and could potentially confuse.

Not bad for a second chamber, I can certainly see what the player is supposed to do in the first room, however, it's completely skippable. The player can use their own vertical momentum to get to the exit door area. Also, there's no sign or antline on the exit door, meaning that whatever I do to open the exit door is guesswork rather than the result of a logical puzzle. You might want to rethink the puzzle a bit to make your intended solution, the only solution.

I've got a little collection of chambers going and I'm always interested in feedback. I'd be grateful if you'd have a look:

Pretty simple, but always fun killin' 'dem turrets!
But, I didn't use the moving platforms at all. What's that about?
