My original intention was to let players pick their cards, but i decided that, at least for the gamejam, it would be beneficial to let them try out all of the different cards, since there wasn't a ton of cards to build a deck around.
If i ever expand on this, that would absolutely be something try to implement.
And regarding the enemy stats- i completely forgot about displaying them when originally designing the UI! So i just kinda slapped in an "on-hover" effect for them. Definitely something i'd try to rework in a full release.
Thanks for enjoying the game!
