Oh boy ! That was scary, this is by far the hardest dual version that I've played.
An excellent puzzle with great logic :steamthumbsup: Favorited !

Hey!!! I loved playing this map! It was so hard, but really rewarding! I might have found another solution too! https://youtu.be/lu0TM87BqBU I would really appreciate it if you guys checked it out! @Mikeastro @Psychological Atom thanks again for the great mind bender!

@Riishuu Yeah, I think you need to redo it again. Cause right now I don't have a special flip panel in my palette to replace it.

I found some pretty big cheese. Never used the far section at all. I did this by bringing the laser cube to the exit section and aiming it at the exit lift receiver. I then stood on the exit lift and shifted the portal slightly so the laser just misses the cube raising the lift. Maybe a portal snap on that surface would prevent this

Excellent map :steamthumbsup:
A bit like the precursor to Self-Isolation #14

@Captain Unhook Long time no see. Glad you enjoyed it. Haven't fixed the middle panel cause I was so busy. I'll get back to it when I have time. :)

What a map! This one took me a long time to solve. There has been one step I just couldn't figure out and I even considered looking at one of the playthroughs in the comments at one point.

Glad I didn't in the end, because it felt very satisfying when I finally solved it :D I think I solved it intentionally, because I used everything (multiple times).

I liked everything about this map: layout, lighting,music, logic and also the thumbnail. Favourited! :)

@jandlml Excellent work solving it, and without hints no less :P I'm happy to hear that you enjoyed it!
jandlml 29 Jan, 2021 @ 5:51pm 
lol nevermind, this happens to me alot i will get frustrated and finally breakdown and ask for a hint and then the solution comes to me. excellent map!! :steamhappy:

ugg i hate when this happens. i think i know the final couple moves but i cant figure out how to get the laser cubes placed properly. i have the connection between the opposite sides just cant figure out how to get a cube through

@Narkodes Thank you so much! I don't know if I should update the map unless @Mikeastro agrees with your opinions. Glad you enjoyed it, though :)

Brilliant puzzle! It didn't take me too long to come up with the final sequence, but the middle part confused me sometimes. Great map, I enjoyed it a lot.
If you have to update the map again, I suggest to use original clean style, moving floor signageto the other side of the button so that it can be seen from the beginning and last but not least, you should turn off the automatic placement helpers of the laser emitter's hammer instance. I had often trouble with that, because the laser ended up being too high.

@Libbybapa Fantastic job! All 100% intended! Glad you enjoyed it :)

Really nice update. Here's the solution I used for the current version: https://youtu.be/5z2TCLAUnQM
Mikeastro  [author] 25 Jan, 2021 @ 3:55pm 
Update: prevented Libbybapa's solution anyway. Puzzle is now slightly more intricate
Psychological Atom  [author] 25 Jan, 2021 @ 12:25pm 
Thank you everyone for enjoying this map so much! Hope you enjoyed it as much as @Mikeastro and I. :)

@Omega Excellent work! Thank you very much for the video. It is almost exactly the solution that I had in mind. I hope you liked the puzzle
@klaus.sfc01 Thank you very much :D Glad to hear that you enjoyed it!

@Libbybapa Thanks a lot for the video! All intended (apart from the thing we discussed :p) I actually had a slightly longer solution in mind myself by overlooking the swap you did at 6:08 but I don't think there's much to do against that. In effect it comes down to the same flow of major events. I'm happy to hear that you enjoyed it!
Libbybapa 24 Jan, 2021 @ 5:02pm 
Ah yes, I missed the obvious - hit the respawn button for the standard cube. Here's the (unnecessarily long) solution I used: https://youtu.be/rUgPaI7lgko

@Libbybapa Thanks a lot for playing! You are correct that some mild repetition is required after placing the pink cube on the right button, but it's not necessary to do everything all over again. The blue laser cube should already be on the island where the second cube drops, which places you a fair number of steps ahead compared to the start of the puzzle.
Libbybapa 24 Jan, 2021 @ 4:36pm 
I enjoyed it. I'll post the solution I used after it is done uploading. There are a lot of steps but there in the solution I used, after placing the pink cube on the fizzler button to the pink dropper area, all the beginning steps are repeated. Is there another way that doesn't include that repeat of moves verbatim? Thumbs up.
