The best game I have played so far! :D
The concept with using blackjack as a combat system is very unique and works well, although it was a bit hard in the beginning. There is also a story which I really like and the artwork is amazing, the music also fits the game.
The bosses are extremely cool, my favourite one was the first one, and I am surprised by how many different enemy types you have created in such a sort time, good job!
