As others have said already, it's hard to plan ahead because it is just hard to mentally visualize 3D rotations of a cube especially when you combine rotations on different axes. The visualizations you added post-jam help a bit but ideally the player should be able to plan several moves ahead, or you just can't expect players to have any sense of self-direction or volition as they're solving any given puzzle.

Many commenters also asked for a grid; to clarify, I think the underlying problem is that the tile art is visually confusing.

My first read of this is that it was 6 tiles wide, so I was surprised to find that it's actually 4. The 3/4 perspective is not helping with legibility either, because at least in my head I start to expect that the squares should be wider than they are tall, due to the perspective skew, which further messes with my ability to accurately measure grid squares. For a puzzle game like this readability is way more important than nice art. For example this is way more readable:

I'm curious if you explored the simpler premise of navigating the dice from point A to point B with the same rules but just in an open area, without the added limitations of bottomless pits? Was that too easy? Too open-ended?

I'm also curious if you explored using smaller numbers? 6 is a little too many squares to reasonably expect anyone to be able to eyeball, but 1 or 2 is fine. Can you still make interesting puzzles with say, just 1, 2 and 3? Have you explored using different rules for how the values change as you move? Maybe the value just increase by 1 every move, wrapping around after it reaches the maximum.

Loved the idea! I think that animations to show the die rolling could be very helpful- I also think that a grid would be nice, and most importantly, I don't have a reference die with me, so I think that some image or some way to view the sides of a d6 could be helpful.

Really only small gripes, I loved the idea and think this was a very cool puzzle game!

Nice puzzle and executed well, though I think some like "next dice" would be great for planning moves ahead. Also, as others mentioned - a visual grid would be nice.

Really cool idea and it works quite well. It's really confusing visually and there should maybe have been a grid of some sort. I had no idea how far I would actually go most of the time

Maybe some better indication on where the dice will fall and which side will be up would be nice. And a grid to help the visual clarity. I found a solution the dev didn't consider ;)

missing that juice :D
the idea was pretty cool.
more feedback for the dice's rotation would help. maybe move indicators (esp since it's hard to see the tile boundaries). this game as a pretty cool rotation indicator: https://nakst.itch.io/dices-odyssey

Cool concept, and was fun trying to figure the levels out. As mentioned below, a small indicator of where you will land would make this game from good to fantastic. Great job!

First of all; amazing job on your game! It fits the theme and is overall nice and polished.

I played through the entire game but I must admit that I struggled a lot with predicting what the actions of my consequences would be. I think a visual indication on the tile where you will land with a ghost will go a long way. I also would've really liked an undo button.

On the whole you made a solid, playable and good looking game though. You managed to keep my attention until the end, and I do not particularly enjoy puzzle games.
