Technically, the game looks flawless; the sound effects and background music are great, the demon's animations are also excellent, and the dynamics of the card interactions are fantastic. Everything looks incredible!
Unfortunately, I don't understand anything about basic card game mechanics, so it was very difficult for me to understand what was happening as the turns progressed.
At the end, I think I got the idea. You did a great job with the tutorials and written tips.
Congrats to the team, I think if you want to continue developing it further after the jam, you'll have great results!
