Thanks for the feedback!
I plan on expanding the game more by adding more game options (for example, customize the number of cards you can draw before the game ends) and more game modes, so I'll probably also include more languages support.
Also, for "bonus" (ability) cards, there are good ones and bad ones, some of the bad ones are not good by themself, but become good when you combine them with other abilities to create strategies.
Thank you again for the feedback and for playing the game :)
