This was a lot easier than I expected it to be, but I still had fun (:

This is very easy, using only two cubes. From the platform where the third cube sits, you can just fling to the exit platform.

Enjoyed it but was also able to finish this with only 2 cubes, I agree you should link the relays to the exit to fix this

Brilliant chamber!
I too did complete your test with only 2 cubes. You can solve this problem by connection all the relays to the exit, so it opens when your puzzle is complete.

Would you mind trying one of mine?

Awesome puzzle! Thanks!
I recorded my gameplay (valve DEM file format): Download [dl.dropboxusercontent.com]. Comments inside video.

Turrets highly explosive. Handle with care

I hate when people say that a puzzle is easy when it's obviously not. Thumbs up!

To do it with two cubes, you just have to make a portal on the floor near where you get the 3rd cube, another portal next to the lift at the door, jump into the portal and bam. You end up at the door.

Got it in two! Really liked the challenge, I spent way too much time trying to only use two cubes, and felt rather stupid when I got it. Nice map though!

Still can't figure out how to do it only using 2. It still is fun. Check out http://steamcommunity.com/sharedfiles/filedetails/?id=153026838 and feel free to look at my other puzzles.

Just one cube. Prepare a cube so it can activate the higher of the two piston platforms that rise to the highest ledge. Jump from the panel that the laser touches and use two floor portals to fling to the lower of the two piston platforms. Portal the laser through the cube to lower the second platform, then ride it to the top. Then fling to the exit.

Nice chamber. I enjoyed playing it. Thumbs up.

Would you mind trying one of mine?

It's possible to complete the map without using the last cube : When you reached the last cube platform, you can use speed concervation and 2 floor portals to go to the exit ^^ For the rest that was a nice and easy chamber.

Feel free to try some maps in my workshop if you have a moment ;)

I like it!

I did it with 2 cubes. Simply making a big jump from the higher gallery.

Goodm map I used all three cubes. Try one of mine. Raycelbelmond
