Thanks for your feedback.
Regarding the UI, I have added a legend to the Itch page to hopefully mitigate some of the issues you were facing. Ideally, this would have been in the game with Toolips, but unfortunately, we ran out of time to implement it.
Animations were also something we had considered, and are planning to add in the future, to increase visual clarity and help associate the cards with the effects better.
Regarding class member restrictions, I do agree that having all the party the same class is frustrating. In the future, there may be more cards to incentivise certain combinations of specific classes. Also, adding weights to the random options may be beneficial, to increase party variety, and minimise the recurrence of the same characters.
Thanks for your detailed feedback.
