Thank you so much! 😁 It's been my dream to make a card game too, I'd already made a simpler system for a previous game (card player versus standard RPG enemy) so I knew I could probably do it. You're right about the time, I wanted to design as many cards as possible and a working basic system before adding too much user-friendliness (after all, what need is there for user-friendliness if the game just doesn't work?). Some systems like the installation cost for the stronger cards were added as an afterthought and forced me to adapt a good chunk of the logic the day before the deadline.
All that being said, the next update will be all about user-friendliness! And then, more cards and a few more mechanics that I clearly didn't have the time to implement. New abilities, a new card type that provides a one time bonus and is discarded immediately, choosing the target of attacks...
