Thanks for your feedback RedHickory ! We are currently working on the translation of every page and a new version will be released soon
In game you have also information on the right side of your screen and here the translation should be ok (you can switch language by clicking on options on the top right corner).
We want to realise an english version of the tutorial but we are also working on a new design for the website so we have to prioritze some functionalities and postpone others. But be sure that we won't forget to do it!
I can explain in a few words how the cards work : you have 5 cards (assigned randomly) and you can play 2 cards and 1 trump (to block others players) by round. Trumps are the 4 elements available on the left side of the board.
You have 7 types of cards and each one exists in the four colors of the board. On the bottom of the card there is a symbol that explains more or less how the card allows you to move. For exemple the Blue Queen allows you to go on 2 blue squares in every direction.
I hope these information will be helpful. Thank you again for your feedback, we will work to improve our game and make the gameplay more clear for everyone!
