Really catchy and satisfying core mechanic! Just rolling dice and swapping faces is unexpectedly meditative and addictive. Love that you kept it simple and focused on testing this core idea — it works.
The game has solid potential to become even deeper. Right now, the progression feels a bit straightforward (just swapping faces for stronger ones). It would be cool to add more meaning and choice to it. For example, if certain faces gave unique effects or synergies with each other, players could build towards specific "loadouts" or playstyles.
Another small point — the rules and logic behind resource drops or events aren't always clear at first. Slightly clearer tooltips or visual hints in the UI would help players plan better.
But the biggest compliment is that even in this form, without a clear end goal and with minimal progression, it's already fun to play. You’ve found a really strong core gameplay loop that stands on its own. That’s the best foundation you could ask for.
Clean, stylish, and very promising work. The best thing I’ve seen in this jam so far (from game desing pov at least)))
