The style that you decided to go with for this game is amazing. I love when people push the bounds of pixel art like this. Gameplay can be difficult at first, especially when having to look away from the boss to check what cards you have. I'm also not a very patient player, and this game appears to reward patience and spacing over aggression. You also have a lot of unique bosses. I've never played Neon White, but this seems similar to that. Nice work!
