Ooh enjoy! Outer Wilds is one of my favourite things, ever.

Counter-point to ConstableJelly (they're not wrong, play however you enjoy, this is just my opinion) - DO avoid guides even when stuck.

The whole game is about figuring things out, looking at the info you have from different angles, or heading out in brand new directions to see if any new discoveries will tie in with where you're stuck. Looking something up will rob you of that discovery and maybe other ones that tie in to it.

There's a great subreddit for the game that is set up with very specific rules to avoid spoilers. You can ask questions there, and people will expertly nudge you in the right direction based on what you've already discovered and figured out. There are communities here also but I don't think they're set up in quite the same way yet (especially as spoiler tags are not reliable in Lemmy yet across different apps etc)

You can definitely do it without resorting to any of the above, but if you get so stuck you're going to drop the game, I'd say ask in that subreddit. Or, feel free to DM me! I'll help you without ruining anything as best as I can.
