The font for the settings and enemy name text is a little hard to read.
I think you have a typo in one of the responses to your new card choice. "I accepts your choice", "accepts" feels like it should be "accept".
I feel like the first level is a bit too difficult, and uses a few too many enemies that require a color of card, as several times I would get none of the colors I needed to take out the enemies, multiple hands in a row.
It would be nice if the music was a bit louder.
I like the creatures that have special effects on turn end, they add to the combat.
I like the atmosphere of the game, I think that you did the dark and atmospheric effect well.
I also feel like the enemies and their descriptions help with the feel of the game.
I wish that there were a few more opportunities to heal, maybe have one of the starting cards in your deck be a low healing card.
I beat chapter 1 on my fourth try, the boss was nasty, but felt well balanced.
After I lost on the second chapter I decided that I was done for the time being.
After a break I continued on the second chapter.
I wish that when you were on your last card/s you could attack for less than would take out an enemy, so that you could lose less HP.
I think that my favorite special card was the attack all enemies one.
I finished the game, and I definitely like it, it is atmospheric and dark, and I think that you did that effect really well.
