Thank you for the feedback!
As I've learned more about card game design I've definitely realized there are some weaknesses in the way this game works. The seed types / card progression in particular is a bit strange, as the weaker cards are literally just worse versions of the better cards and are therefore not great to add to the deck (as there's no way to get rid of them).
I would still like to come back to this game and expand or polish it, but I'm not sure exactly what I'd like to do (...or when I will have the time and motivation--although seeing people continue to enjoy the game definitely helps on that front!). The idea to make the win screen more satisfying is definitely a good one! And I agree some overhaul to how the seeds work is needed.
Maybe one day. Until then, thank you for playing!
