you are very creative, I'm enjoying your chambers.

Very interesting!

Nice job good tests

now that is fun

Cool fun game.
[Tom K] Dec 20, 2015 @ 8:56am 
Very cool mechanics in there, nice map!
rulestheworldasaurus Oct 13, 2015 @ 1:27pm 
Wow, great level... and inspired by REAL PHYSICS no less! I loved it! Kind of looked like the Turret hit the ground first, then me, then reflection cube, then weighted cube.

nice map !
PortalFan Jun 28, 2015 @ 5:15am 
Original mechanism, good map !
akross.cs Mar 24, 2015 @ 12:58pm 
nice designed puzzle but very easy
Frezzer Jun 26, 2014 @ 3:41am 
another great map thx :)
private.way Jun 17, 2014 @ 10:04am 
A bit of a chore...tiresome -- yet great thinking at the end....overall nice.
p0rtalthumper May 30, 2014 @ 4:57pm 
OK, so a turret apparently falls slightly faster than anything else and yet it can't weigh down buttons unlike in the original game....strange indeed.
robin_z May 27, 2014 @ 12:29pm 
Took me a little while, but eventually figured it out. Thank you. :)
Petutski Apr 2, 2014 @ 2:10pm 
Very nice. Ejoyed it!
claymckelvy Jan 24, 2014 @ 1:27pm 
Pretty test. I did not find it difficult, but it was fun.
Lepo Jan 12, 2014 @ 10:12am 
Very original, very clever, it's fun to play, but not perfect. The trick with reflection cube could fail if not perfectly positioned, and the last jump require a bit of timing. As for difficulty this could be between easy and medium. 7.5/10

very awesome

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

Turrets highly explosive. Handle with care

Some of those things I hadn't seen before.

Challenging Chamber, I enjoy challenges, Please give my chamber a try was hard to figure a way to use only 4 gells and no other items and make it challenging the name of the mape is Gell-O here is the link if you beat it leave comment thanks. http://steamcommunity.com/sharedfiles/filedetails/?id=162320338

A lot of game mechanics I haven't seen before.

This is not a puzzle map. This is a hardwork map. And when you just land the cube on the button it dissapears because of a stupid placement of that blue thing.
Databot1 Jan 27, 2013 @ 1:14pm 
Fantastic concept! Deactivating the parallel light bridges is a little cumbersome due to the quick deactivate/activation jitter, but really great overall
Ambrusius Jan 14, 2013 @ 11:20am 
awesome map, not to hard.. not a complete timewaster.. perfect amount and epic for curing boredom :)
hats off to you!
Bayram Jan 12, 2013 @ 3:08pm 
Short and easy (it was pretty obvious what to do) but strangely satisfying. Everything worked perfectly the first time.
herbusmc Dec 22, 2012 @ 1:41am 
Nice map The last bit doesn't work every time. If it did I would have ben done a lot sooner. nevertheless it was pretty cool. Thanks.
Fredouillelafripouille Dec 17, 2012 @ 1:36pm 
Nice idea. But a little easy, I find.
'going to test next chambers... ;-)
Rapczynskier Dec 15, 2012 @ 10:02am 
Nice trick with the light bridges
tuyuqas Nov 24, 2012 @ 3:16am 
Woow. Had to think for a while :D Very nice job!
big body bes Nov 19, 2012 @ 7:13am 
That was really great! Getting ready to play 2 and 3, but really! Good job man!
Andi Nov 18, 2012 @ 3:14pm 
A very inventive solution. Dispite the fact that it didn't work according to plan all the time, it was fun and enjoyable nontheless. Thumbs up.
Positron  [author] Nov 16, 2012 @ 7:30pm 
Part 3 is finally here! It is similar to part 2 but has a different focus.
Bellomy Oct 22, 2012 @ 8:19pm 
Hmmmm, an update for you. I tried to recreate the level with the ninja solution. It didn't work this time. I had to use the original concept to solve the level. Perhaps a flluke? Either a glitch or pure dumb luck?
Bellomy Oct 22, 2012 @ 7:37pm 
I really hate to be "that guy" but...I found a "Ninja" solution! There is a way to solve the level that makes the reflection cube completely unnecessary. In fact, the entire system of light bridges, buttons, fizzlers...all of it is completely useless if the Ninja solution is found. It's not obvious but once you find it you'll hit yourself in the head because it's REALLY simple. It's a shame because it's such a nice concept, but there you go.
gibplumber Oct 17, 2012 @ 12:23pm 
Absolutely amazing concepts. Although ingenius on their own, I hope to see them as part of a larger test chamber in the future.
I Kinda Fail Oct 16, 2012 @ 10:46pm 
Twitchy laser puzzle, but a pretty good map. Loved the ending.
Toaster-Oven Oct 13, 2012 @ 7:50pm 
For a strong concept puzzle with a fun ending to watch try this one.
Toaster-Oven Oct 13, 2012 @ 7:46pm 
Wow, flawless timing all around. One of the best.
Mr Fraggle (UK) Oct 13, 2012 @ 2:16am 
Very nice and a lot of fun.Well done.
Penta-Tonics Oct 12, 2012 @ 9:12pm 
I loved it! It was a well thought out, well designed map. The one thing I liked the most is that you did not make it too difficult. You were stating a concept, and how to use a couple small puzzles around the concept. And that, my friend, is a hard thing to pull off. Most beginner authors would either make it mearly a concept map with no puzzle, or they would make the puzzle so hard that the player would miss the point completely. Thus, I congradulate you.

On the fling puzzle, if you were to place the light that's next to the button above the faithplate, then the player would know where to stand better.

If you are interested, here's a map I made recently that you may enjoy:
Mr.Johno Oct 12, 2012 @ 12:55am 
This is brilliant, i didn't have any problem, but i love the ending.
ExciteWalk Oct 12, 2012 @ 12:22am 
Not sure if I did it right, but the disabling the bridges was a "twitchy" process. A bit annoying and somewhat frustrating. I would suggest nudging the laser emitter closer to the wall.
RichardPrime Oct 11, 2012 @ 11:07pm 
Been a while since I tested a chamber that is so terrifically creative and unique. Well done.
NyanNyanKoneko Oct 11, 2012 @ 9:36pm 
Clever, but a bit "tricky" in how you get the cube onto the button on the ground.

I liked it. Good job.

Hey this is a great map! But I replayed this and I somehow got flung into the void?
Try out my new map here!
