Pretty nice !

Great map, nice work on redirecting the laser to the catcher(s).

Thanks for playing, Mitch McWiggins! Glad it worked for you. If you enjoyed this chamber, you may enjoy the rest of the series: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=197052794

At first I was worried, but all of this was fun and challenging, thanks.

Thanks for playing! Glad you enjoyed it!

The grid is, indeed, to prevent that glitch. The main point of all the grating is to force you to use a new method for tipping the cube ( using portals ), and that new method might be overlooked if you could glitch a cube in with the other cube and use one of the cubes to tip the other.

That noclip cube glitch tends to happen frequently in my chambers. Don't know why. =-/ But fortunately, you can still pick up the cube, and so the new tipping method still works just fine. Well, and I guess fizzling fixes it, too.

I see you added a grid over the portalable surface where you enter the test. I gather that was to prevent the glitch where both redirection cubes might wind up inside the cage.

I had a weird glitch in the last part where I couldn't nudge the redirection cube into place; I would just walk right through it like it wasn't even there. But when I fizzled and respawned the cube everything went back to normal.

Great puzzle, especially the finish!
