That’s fair, it is slow and often clunky. I am personally totally fine with the pace of it, but I get why it wouldn’t be for everyone.

To me, the ship navigation stuff was there to make the setting feel bigger and lend weight to the plot rather than the puzzles. I personally enjoyed stopping off at unexpected things I found along the way, or figuring out how to get to some of the less-accessible worlds (the marketplace at the very top left of the map stands out to me here). I’m okay with it not being a tightly-focussed puzzles-only sort of thing

Edit: possibly relevant, apparently the game had some pretty bad bugs with the navigations on launch. I played it after those got patched, so my experience may have been different to yours
