Thank you for playing our game and for your comment, LRFLEW!
We did some playtesting with the stars minigame and found that it was too difficult to guess what the constellations might be, hence we added the hints in response! I guess we needed to either keep them up for longer, or give the player the ability to display them again haha. I think the colliders for the stars should have been bigger in retrospect, and expect that's the reason behind the bug you've described.
We had considered branching dialogue paths as a larger aspect of gameplay, but found that ultimately we needed to restrict them in order to finish the game over the time period. If we develop this further, I expect that branching narrative will be something we get to give more attention to!
