First of all, I loved the game! I had some questions/nitpicks, though:
1) Why is some art so much more detailed than others? ex. the witch's overworld sprite and the witch's dialogue image
2) Does the black deck only have the double damage card?
3) Some cards have titles in all caps, when others are normal.
4) The player's hitbox is strange, as I think shots that hit the player's head just go through.
5) It can be confusing how the Goblin bomb thing releases blue projectiles instead of yellow.
6) Is there a way I can get into the basement again, or does it have no more use after defeating its boss?
7) Will there be a steam version or any more updates / anything more of the game?
