We skipped right over the opportunity for non-integer fractal dimensional chess! In all seriousness, this looks super interesting. I’d love to see some live gameplay of it.
This is kind of the opposite. So it really competes with Fall Guys then...
It looks amazing, and I really want to play it, but however I count I only end up with 4 dimensions. A chess board is 2D, time back-and-forth is 3D, and going up/down across universes is 4D. What's the 5th? Are they counting real-life-time as the 5th? In which case normal chess is 3D, which seems like an abuse of terms.
I think you're right. Even if we classify classical Chess as 3D (2D board + a time axis for game states), time travel re-uses that same time dimension.
If you wanted to shift the complexity into ludicrous speed (this is inspired by archgoon's comment [0]), you could introduce another dimension by putting a classical chess board inside each square of the 4D board. The 4D move only succeeds if you win the game on the mini-board. Just, please, don't bring recursion into this, unless you're captain Kirk and absolutely need to nerd-snipe a rogue AI. (“They've gone to plaid!”)
There's another possibility I've hinted at by calling standard Chess ‘classical’. On second thought, let’s not go to Quantum Chess. 'Tis a silly place. (I tried to imagine what a Schrödinger's king would look like. I've seen things you people wouldn't believe. Queens checked en passant from the future. I watched knigths glitter in the parallel time-line near the Hadamard Gate. All those moments will be lost in time, like tears in rain. Time to resign.)
When I was learning about puzzle game making, one of the rules was people don't like puzzles. They like puzzles but not the feeling like they're doing one. This is kind of the opposite. So it really competes with Fall Guys then...
I always thought a cool chess variant would be quantum chess where you can move a piece to more than one square and assign a probability to each position. Your opponent could do the same. But I never worked out how it could work from there.

If the chess board is 2d, how does the Knight move, doesn't it need the third dimension to go "over" other pieces? I assume, graphics notwithstanding, the board is logically represented in 3 dimensions.

If you add probabilistic moves, the optimal way to play would be to give each alternative move the same weight (ie probability) that you think it will win you the game. You would pull this probability out of your mental representation.
Something like, "I think this is the best move, but this one is really good too so I will do it as well".
So I guess it could be fun to be able to try out all the moves you think are good in this way. But then an easier way to achieve this is to just play the game normally and go back to an interesting previous position once you have won.
But maybe a set of rules that will allow you to still win the game 'in retrospect' after all the 'best' moves were played by going through all the alternative superpositions as well.
So basically just play normally, but when you doubt what move is best, you make a superposition (and assign probabilities), which means you will be going back to this position later.
The winner would be the one who won most often, with each win weighed by the probability of that outcome (calculated based on the assigned probabilities along the game).
Sounds like fun.

It's only 4D. I believe they called it 5D chess because they didn't want people to interpret this as 3D chess + time. If I recall correctly, the tutorial mentions at some point that the 5th dimension is "unused".
It would have been nice if 4D only ever meant four spatial dimensions, and then we'd have (3+1)D for three spatial dimensions and a time dimension. (And (2+2)D for two spatial and two time dimensions :-))

So checkmate in any one timeline counts? You couldn’t do all timelines.
I suppose you would have to avoid the king escaping to another timeline?
