@Mattchew that's pretty high praise. You sure you just haven't gotten to the good workshop maps yet?

Even after a couple of weeks, it is hard to put into words how much I love this map. New personal favorite!

Hard work! ^^ I was clueless for quite some time and felt heavily restricted. After all the ghost maneuvers that popped into my mind little by little, reaching the exit felt so rewarding :-)
The null portal move was also very clever. After it happened by accident it took a few more minutes for me to see that it was actually helpful ^^
Agree with Narkodes about the grated panels being too dark, though I see your hint in the design (panels being carved out and with white edges and lightstrips).
Didn't experience Nobody's and Mikeastro's confusion with the exit surface. Imo it's clear that pushing and/or pulling a cube here makes no sense.
The final two sacrifice timings were pretty tight (yet feasible). Let's say there was no risk either since you can rebuild the setting easily.

Tricky one! Glad I figured it out, had me puzzled for a long while

I still love this :D

Very nice cube stack puzzle! I like how you worked in that it has to be done multiple times.
Mikeastro 1 Apr, 2022 @ 11:54am 
Very nice map. I experienced the same confusion as @Nobody No-One. Big thumbs up :D

Really nice map with a remarkably elegant setup, and I always love a good ghost cube maneuver. My only criticism is that the grated surface you use to get to the exit is a little bit of a red herring, since the fact that it's directly above a button is, as far as I can tell, not relevant to the puzzle. Big thumbs up.

The map is short and noice. I rlly do like it! :D

Very nice!

@crhoaviet6 I think as you play more and more puzzles you'll become familiar with those types of maneuvers. Thanks for playing!

Excellent puzzle. I finally threw in the towel and spoiled myself. I'm a ghost cube newb, so I don't feel too bad. The cube reversal is clever - I love that kind of thing.

Wow, this one's giving me a hard time. After an hour, I haven't even gotten the black cube out of the entrance area. Very intriguing.
Dolphiner 7 Mar, 2022 @ 8:04am 
Brilliant job with this! The cube stacks to get the black cube out of the starting area and then twice to get the reversed funnel in the exit area were very satisfying to figure out Favourited :steamthumbsup:

Gotta stack 'em all ! Good stuff :]
hfmanson 5 Mar, 2022 @ 12:01am 
Very nice concept!

Awesome map. I played the very first iteration, so I already knew the solution. Glad to see the updates improved it. Unfortunately, 2 white surfaces with grating are barely visible now. If I didn't knew the solution before, I'm not sure if I would have ever shot at those. Maybe different grating wouldn't cast such a massive shadow? Anyway, fantastic sequence. Big thumbs up.

Very nice! Challenging puzzle, good clean architecture, 10/10! Thanks for this map!

One of the best I`ve seen

@bullfrog All intended! Thanks for playing.
bullfrog 27 Feb, 2022 @ 12:42am 
And just to check: intended solution ?
bullfrog 27 Feb, 2022 @ 12:34am 
Ah, @Dark Rozen's link is a screenshot, not a walkthrough, but it looks like it was taken from an older version and is no longer valid?
bullfrog 27 Feb, 2022 @ 12:21am 
Excellent puzzle, definite :steamthumbsup: I'm pretty sure I solved it as intended, but I'll record a walkthrough if different to @Dark Rozen's.
Frigga 26 Feb, 2022 @ 11:51pm 
very cool map. nice use of funnel and lift. and what has been mentioned by Teo, the cubestack definitely a big thumb up!
Psychological Atom 26 Feb, 2022 @ 4:34pm 
Very awesome map indeed!
Dark Rozen 26 Feb, 2022 @ 9:41am 
Fun map intended?
Teo 26 Feb, 2022 @ 9:10am 
Really damn good. I like how open the map feels after leaving the starting platform for the first time, but actually there is only one correct path. I also love how the cubestack works both with the piston and funnel; I didn't expect it to grant enough time at first but was very happy when it did . Great work!
nerdlingnation  [author] 24 Feb, 2022 @ 11:48pm 
@Aneonen ah yes. Forgot about that exploit as I was taking my final pass at the chamber geometry. Thanks for pointing it out; should be fixed now.
Aneonen 24 Feb, 2022 @ 11:14pm 
Nice puzzle! The rising platform was a smart approach to the theme. I performed what I assume is the intended solution, but, uh, the player can place the white cube aside the floor-button-aimed faith plate and slide it over with the funnel while near the exit to skip quite a lot; maybe worth adding a note?
