You got me frowning because I was expecting the names of the suits to be "Cups, Staves, Coins, Swords." It's a good indicator of how amazing the game is that this is my only issue.
Thank you for your kind words and I hope that the finished version is even more enjoyable!
as for the coins, tbh we just directly translated it from spanish, coins is called "oro" which means gold, and in the rush of the game jam we just went with it, we realised later the name was incorrect.
As for staves, we usually find that both clubs and staves are used interchangeably, maybe it depends on the culture?
