Thank you for trying it out!
It was truly a mistake on my part that the replay button didn't work properly and send players to a test scene that were not meant to be player-facing, instead of sending them back to the correct level.
I meant for the cards to be a little off-screen for real-time gameplay but you can pause the game with right-clicking anywhere else that's not the card on the screen to bring up full visuals of the cards. I should totally have put in a tutorial for everything in the game.
I'm also really sorry that I wasn't able to play and rate your game before the end of the rating period, but I'll go try it out and leave a comment on it!
