Yeah, but I'd have to enclose the area above that entire last corridor in glass, sides and top. Pretty ugly. You're probably right, it's good enough.

I agree, no one wants the lasers. :) Maybe a pane of glass on the above-the-grating level, near the exit, blocking such an exploit? Either that or don't change a thing, it's fine.

That's true. Dang. I was not expecting it to be that easy to turn cubes vertical, especially with limited head room. The only way I can think of to remove the four-cube solution is to replace the grating with a laser field, but I really don't want to do that.

I did it with all 5 cubes this time (I guess I was trying to take a wrong turn originally--went down a different hallway this time and I had enough cubes; not too many corners) but it looks like I would still be able to beat it with 3 cubes, by portaling the laser through the floor, catching it with a cube on top of the grating, and route it the rest of the way the same way I did in the screenshot. Is the portal in the floor in the middle necessary? If not, maybe the portalable surface could be on the walls in that hole instead of the floor. But, then, one could still beat it with four cubes instead of five... Anyway, good one. Thanks!

Whoops! That's an embarrasing hole. Thanks for the screenshot. That portal surface on the ceiling isn't even necessary for what I thought I needed it for, so I removed it.

Bending lasers around corners is precisely what reflection cubes do . The key hint for the intended solution is "planning ahead".

(3 cubes)

Here's the only way I can think to do it. Warning to others: spoiler. screenshot
Not sure how I'd do it another way, bending laser around corners...

Haha. You're supposed to need all five to solve it, but now that I've thought about it I found a way to do it with just one.

Now I think I've nixed all the shortcuts I know.

Good one. Intended to be solved with just 2 cubes, right? That's the only way I could figure, anyway. Thanks! Here's one of mine in case you haven't seen it already.

Cool practice. If I'd have had that room before, I wouldn't have needed so long to find out, that this shall be the intended way for the 'real thing'. #F4F
