I'm a big fan of the tri-fold (bi-fold? idk) pamphlet format. I think there's something very pleasing about the ratio of width/height, I like the tactile nature of the folded pamphlet and the limited space means you have to think really hard about what is truly essential to the game.
That said, one of the problems with that format is that it can be a little bit hard to parse which part you are meant to read first. As a reader, I felt a bit confused here as to where to start and that meant I only got the rules properly after reading the whole pamphlet a couple of times. That said, it's not a lot of text so it's not a big problem by any means, just an observation. The fact that you have the stat blocks for the different worlds on a side that you have to fold over to meet the map was clever, but it took me some time to realize that is what you were meant to do (I think?). It also took me an embarrassingly long time to realize that the track of circles in the middle panel was the map. This probably says something about my congnitive abilities, but maybe it could be more clearly indicated on the pamphlet what is the map and how you are supposed to use the map with the stat block for the worlds? I'm also a bit confused about how exactly light lag works and how it affects play.
The game focuses pretty hard on mechanics, and that's fine of course, but I was left with a bit of uncertainty about how the game plays differently as a single person game as opposed to having more than one players. The game doesn't really tell you how to play it as a group, so it feels maybe more like a single person game where you're trying to beat the game. That is a totally valid design choice, of course, just an observation.
All in all, I really dig the theme and style of this game, there's a bit of understated humour in it as well that fits nicely. I think it seems like a fun game that you can easily carry around and play in a café or something.
