Card variety seems like a common, reasonable comment. I played through the full game and it was cute and fun in its own little way.
more cards would be nice as it does get, rather boring, especially when going for the second ending, after whichever you picked first.
but for what it is, this game is quick, a small project, and thats alright, not everything has to be a ff14 sized MMO yk?
keep up the good work, ill be looking for more of your stuff to come.
