cool idea! i had fun playing :)
first i tried without reading the rules and thought that two cards of the same vegetable would bring me luck haha
after looking into the rules it got much easier! love the mechanics of spotting the rabbits, a bit of detective mode ^^
would love to have an in-game tutorial :)
also do i understand correctly that the only way to finish the game is "stop the harvest button"? if that is right, i would prefer to see some encouraging words there, like "good job!" or something depending on my score instead of "game over" :D
great take on the theme!
