It's so creative and funny puzzle with laser technique.

Very clever concept. The second part took some trial and error, but it was easy to figure out once you have tried and eliminated other potential solutions.

A perpetual motion machine ! Always really clever

Easy compared to the other ones, but I appreciate the innovative concept!

easiest puzzle you have ever made :D

Really nice concept, I never know this can be done, might be a direction you can explore more. Nice tutorial also to help with the next step.

It was really clever to center the test chamber around the concept that a laser emitter can power itself.

Nice one

oh how I hated timed things

как и всегда- nice!:steamhappy:

Not sure why the first area exists, the second area is easy enough to figure out on it's own... Still a neat map. Difficulty, easy, at least for me, yet still a fun and clever idea rarely seen before, I like the idea of initially powering what you need with a timed laser but having the cube redirect it at the right spot into a laser catcher activating a laser that will be able to self power itself in time. All your maps are based on ideas rarely seen before, I like it! Continue the good work :)

Wow, that was something I hadn't seen yet, very impressive.

latching on yet?
Petutski 15 Apr, 2016 @ 1:40pm 
Nicely done with a "training" pre-chamber. Thanks!
N Twirl 16 Mar, 2016 @ 8:30am 
So dam good.

Haven't seen that concept before. Really had me stumped for awhile in second room. Mevious is the BEST.
Pamsy 4 Jan, 2016 @ 9:27am 
Nice concept, solution easy to execute. Hint: move input portal from laser 1 to laser 2.
Spaceminnow 23 Jul, 2015 @ 10:11pm 
This laser puzzle is one of the best I've seen. Excellent !!! :D
HJN-DK 20 May, 2015 @ 5:32am 
Clever concept!
Shepard 10 May, 2015 @ 9:32am 
Easily my fastest Mevious solve to date. Less than five minutes.

Really like the concept though!
m00ny 13 Sep, 2014 @ 11:36pm 
something new. thanks!
Afterglow 15 Aug, 2014 @ 7:23pm 
What a cool concept! I'm kinda surprised it works, but wow! And it wasn't very hard like your other levels.
Angel_iKaroS 25 Jun, 2014 @ 2:09am 
Not hard but very inventive
joe 7 Jun, 2014 @ 9:49am 
Genius as always. Capture the laser in a loop that allows you to move the cube (ignore the lift activaters at this stage) then very carefully align the freed cube back so that once the portal is moved to activate the lift the loop is not broken. Fantastic.
Petutski 8 Apr, 2014 @ 2:41pm 
Excellent chamvber, but not auto powering as some have said, but auto-enabling.
colin-java 2 Mar, 2014 @ 8:49am 
That was mad, 2nd part was a slightly harder than first, but if you think it through its not too hard.
Kbeam 1 Feb, 2014 @ 11:57am 
Wow, excellen idea, did not see parpetual lasers in the main game, what a nice idea!
stormsend 27 Jan, 2014 @ 1:10am 
Very nice as usual. Good logic. Not too hard. Good looking chambers. Thanks.

I love lija's comment, because there is truth in it. This was a nice and easy map compared to your more serious work. I love laser puzzles more than most, and this is no exception to that rule. Keep up the stellar work, my friend!

infinite energy, really does work!

Mevious, you are the BEST puzzle designer in the PTI. Your test chambers are both challenging and very satisfying. Some user made test chambers contain a ton of gadgets but are usually more like a "goose chase" than a true puzzle. But not yours. They always contain the bare minimum so the player MUST think things through to solve it. Some of them took me a while to solve and I like that. Respect baby!!

Awesome puzzle. Very funny. Thanks.

This is extremely awesome! The thought of "Laser-Ception" is just pure epic. Good job.

You, sir, are a genius

Nice map, thanks.
SeraphMan 17 Jul, 2013 @ 12:54pm 
I'm glad to see this was just a tutorial, because it was rather simple. The only difficulty was in the precision needed with the cubes and portals. This is definitely something I want to see fleshed out.
EvilHeavy™ 10 Jul, 2013 @ 6:12pm 
Whenever I see a chamber by Mevious, I go "ugh" because I know it's going to be hard, however this one right here has proven me wrong. Well played, Mevious, well played.

Refreshingly straightforward and simple.
