I really like the atmosphere you're creating. Unfortunately, I have no idea what I'm supposed to do. Is there even any endpoint yet? I.e. am I supposed to ping something and get a different answer than "there's nobody there"? If so, the game honestly doesn't do a very good job of clueing me in on it. It feels like I would want to look for stars that have potentially habitable planets and ping them in hope for a response, but so far, that doesn't seem to be very successful.
I know that the dice rolling mechanic was part of the GMTK jam, but now that the jam is over, I would consider removing it. If this is supposed to turn into a game about exploration and mystery-solving on a timer, don't make that timer random. That's just not fun for the player.
While I do like the visual style quite a bit, I also really dig the text input system and I wonder if turning this game into a completely console based oldschool text adventure might be a fun thing to try. Would turn the game into even more of a niche than it already is, I suppose, but sometimes it's better to create a great game for a small target audience than to create an okay game for the masses (or at least that's what I tell myself while I keep making hardcore puzzle games with insufficient tutorials and wonder why people don't praise me as the greatest game designer of all time).
The ticking of the clock felt a little unnerving. It might very well be that this is the feeling you were going for, but I could just as well imagine this as a very contemplative, quiet game. I think that's a stylistic choice you'll have to end up making for yourself.
Finally, I think the mystery in this game isn't really doing enough to keep me invested in it. Why do I care? What reason do you give me to care? Who even am I? Am I just an scientist who's making objective observations or do I have a personal reason why I'm searching the stars for something? I suppose maybe I'm looking for signs of life, but why? Do I just want to know that it exists? To I want to make contact? Do I want to go there myself? Do I hope to be saved? Do I hope to save somebody?
These are just examples for questions that might help to establish an emotional connection with the game. If players don't care for your mystery, they won't end up solving it.
Okay, sorry for maybe sounding a bit negative here. It's just that I really like the idea of a mystery that can be solved by gazing at the stars and I feel like this game has a lot of untapped potential. The atmosphere is already pretty good. I just think there needs to be a little more guidance in the mystery solving process and a little more reason for the player to actually care about it.
