Didn't need to do the floor laser catchers in the first and second room (with the turrets), didn't need the weighted cube.

good but skipped the whole first room.

A win is a win... but I got the feeling, as I went through the exit, that there was more to be done that hadn't. A cube unused, a laser used once when other elements were used twice. Still, enjoyable.

In my profile screenshots, I have antline tricks that your puzzle can benefit from so that way you don't have to hide or use symbols.

For the 5 turret laser room (just before the light bridge to the exit), put the reflector cube on a pedestal activated laser cube dropper. Trust me on that. It is possible for the cube to be protected by the turrets indefinitely with no chance to outwit them.
