This is surprisingly great! The best game I played from this jam so far and one of the best jam game I ever played!
When I read "inspired to Outer Wilds" in Discord, I thought to myself "No Way!", but this game totally delivers. It took me ~30-40 minutes to beat without hints.
I think you are overly explicit in some sections, where you outright spell out the mechanic, which I already figured out by that point experimentally (at the same time, I understand, that for a jam, it's better to make it too simple than too hard).
This has to be selected by Mark.
