The polish is on point, I love that you based everything on the BPM, it creates an engaging battle.
I managed to beat normal on my first try, but impossible is a struggle. But I did manage to get the 53rd card!
Thanks, I was addicted, when losing I really wanted to play again. The text to invite you to change difficulty after beating the game is a really smart touch to get us to more content and reward players!
I had a lot of fun, congrats!
