Real interesting, very nicely done and fun!
Will say that unless it's full screen it's a little difficult to see what pieces are what on the black space, could maybe make the pieces a little brighter, or you could have a little text box come up when hovering over the pieces that says what they are and how many points the piece gives you for taking it since you can upgrade that in the shop
Having cleared a board and still losing is a little sad, could maybe have like a "last piece standing" bonus points thing? Not 100% necessary I don't think as you shouldn't really have it happen unless you blunder/haven't bought the right items
I also got a build going a few times that straight up carries lmao, managed to do all of Ante 3, Ante 4, and all but the last one of Ante 5 in one turn, which I think might have been a little easier to get due to how few artifacts there are atm, which I imagine will change as you develop the game more
I don't really have anything negative to say I guess, great game! I look forward to the following updates
EDIT: Bug found, I pressed to play again and it kept all my artifacts from the previous run
