I like the idea of gardening themed deckbuilder!
As of now, the gameplay seems a bit flat. There are no interesting decisions to make, I just plant all the plants next to each other and scare away the crows if I get the card for it.
I personally dislike any lootbox adjusted mechanics in my games, so I did not like buying card packs, but it is a personal preference.
I think this game can turn out really interesting if you make it a bit more dynamic. If plants gave me coins and disappeared when they are fully grown, I could cycle the plans and time the use of other plants and tools to maximize the coin gain.
