I'm a little late to the party on this one, but I have to say this game is extremely well made!
I expected this to be a short 5 minute game (being a jam game) that would be fun but not very fleshed out. Man, was I wrong. This game honestly felt like some sort of pilgrimage or something. I think it took me about 50 minutes to beat the game!
There's pretty much no hand holding to what you "need" to do, but once you figure it out, it does become slightly clearer what you need to be doing.
I HATE first person platforming in games, but very surprisingly, this game controls very well, so it's implementation is not frustrating at all!
The game also has a beautiful PS1 era aesthetic, that really reminded me of the PS1 version of Myst.
All in all, this game was fantastic, and you get a hell of a lot of experience for a free game, definitely check it out!
Here's my playthrough for anyone interested (I did find all starseeds):
