Just some random thoughts from a few hours play.
You are obviously meant to revisit your start planet as there are many things on it you aren't equipped enough to do, I found a manufacturing plant with a door I can't open and an observatory that needed a specific crafted item to enter.
Don't like the dumbed down ship surface flight, the auto altitude is just bad.
I like the maths puzzles!
There is no map?, does one ever become available?, navigation can be an issue.
It can become a struggle to know which items / species you've scanned.
There are ALOT of resources.
You pretty much can't do anything without resources, what you take off?, that'll cost you plutonium, your suit needs a constant stream of resources too.
Blueprints I've found so far aren't worth crafting, they don't offer enough of a stat boost, and take up a valuable inv slot.
There is ALOT of inv juggling.
You can't mine (at least I can't so far) everything, only things that show up as a mesh when scanning, so you can't terraform the planet.
Some of the creatures just look........bad?, they just look like bad spore creatures!
I sorta like the "choose your own adventure" options you get from aliens and monoliths, but I wonder if there may be a lack of depth.
Overall, an interesting game, barely scratched the surface yet.
