Great balance of the three assets (production, research, and armanda strength), good UI, nice cycle length, strong theming... Great job!
If I can make a suggestion, though - the 'pity' stardust the player is guaranteed every cycle is brilliant, it keeps forward momentum going, but it does mean there's a bit gap for the first... hour?... where failing or succeeding in caching data just once is functionally identical. Because succeeding twice is several meta upgrades deep, it leaves the player in a place where abandoning a dozen or so cultures as soon as their cycles start is exactly as effective as trying their hardest for those cycles. This becomes apparent about 20 minutes in, at which point I almost walked away. Consider just having 1 stardust as a base, with each success adding 1 to the counter? There would be a reason to keep engaging with the game in that case.
