Thanks for all the great feedback, I didn't have time for much playtesting and had to hope the game magically works when I submitted it. I will try to address some major point's you made
4 - There is in fact no limit to any stats.
5 - Level Design is defiantly one of my weaker points, I do plan on making that change in another build where I polish a few things up.
6 - My guess is you might've had a card selected without notice, like your second point I do want to add that highlight feature.
7- With how I have the cutscenes set up right now, make the text scroll faster upon input would be impossible, I can make whole cutscene skippable in the next update
8 - It's a hold over for a not fully developed part of the game. Your deck was supposed to resemble your character's slowly withering life, getting weaker as you went on. You initially get a deck size of 20, and getting 5 from enemies, losing cards upon draw. The sticks were there so you had at least something when you ran out of cards. I'll probably just give you cards in a never ending deck so it's playable from start to finish.
And for the ding part, I did fix within an hour of my original upload, although there are still bugs associated with that.
Your review was really useful in helping me know what I need to improve on.
