[Coop] Lessons Learned
Really amazing puzzle! Congratulations guys! 
Lp and I was playing and to be frank, I didn't find any bug or missed much detailing: the details are indeed very close to be the exact amount of them! On the other hand, the puzzle was really clever, and a balanced level of difficulty, thing quite difficult to get! Good job.
It is quite tricky
I will stay tuned to your work as this one left a really good impression.

Nice one! The solution should be so obvious since there is not portable surface in the second room - yet it took us incredibly long to figure it out. Small but tough and using a lot of cooperation, very good. 5/5.
@chickenmobile: Maybe you should add spoiler tags to your post?
Glad to hear that everybody seems to be finding the correct solution, and in an amount of time that is nether boring nor frustrating. So far at least.
After my last map and having spent a couple weeks on just the details, I wanted to start a series of small/clean maps that could be built, tested, and released in under week while still being interesting to play and solve.
With as good as response as i'm getting so far, I'm working hard to have my next map finished very soon. Which btw, I am always looking for testers. Send me a friend request, I'm "Nautik" on steam. I pretty much accept anyone so if your interested don't hesitate to add me.
What an apt title for a map! If you can sit through our 43 minute blind playthrough, you can see how we learned a few lessons along the way. I definitely figured out why the pit of goo was there, for example.
The looks were plain, but not unappealing. We were concentrating so much on the what and the how that we barely noticed the where. My only negative comment about the looks of the map was the size of the rooms, which I didn't think needed to be nearly as large as they were. I certainly wouldn't rebuild the entire map for that weak a complaint.
The puzzle was excellent and required good cooperation when you were doing it right. However, when I screwed up and trapped Redunzl in the final room, I had to re-solve almost the entire puzzle by myself to get him out. He could have committed suicide, of course, but what's the fun in that?
Overall, the quality of the puzzle almost lifts this to a 5, but the length and setting are not quite as good as other maps to which we give the highest rating, so 4/5 from us.

Iviv and LyLy here, and we just played Lessons Learned. Might we say that this is a very superior map! It kept us thinking and moving without being frustrating in the slightest. One of the best puzzles we've had the honor of fumbling our way through!
Thanks for the playthroughs and comments everybody. I'm glad you all are enjoying the map. And wow, still a 5/5 rating after 11 votes (as of now). I didn't expect my first "release" to do so well.
That map took me and my partner by suprise. We are demanding in terms of quality of puzzle and this one definitely delivered. Took us around 30 min. but this required fresh ideas and good cooperation. Personally as for puzzle itself is in my top 5 cooperative maps. Really excellent and gave us a lot of joy. In my opinion as bug free and puzlle quality this should be moved to community spotlight. Eagerly awaiting for new releases. Many thanks
Wow, you guys are awesome, this map and FloorPlan double featured in the community roundup and moved to spotlight. Thanks to everyone who played and enjoyed my maps! 
Thank you for making this map, I enjoyed it very much. I love this kind of construction where it is quite easy to see every element but the solution is still far from being straightforward. Not terribly crazy difficult either. Some serious logical thinking is necessary, but it does lead to the solution. This map is a little gem worth treasuring.
