Very well made for only 2 weeks!
The graphics are really good, the audio too.
The unexpectedness is the kind I don't like: randomness. When the blue enemy changes the actions, you can take a lot of damage at the same round. I think that if the player's life regenerated one point at the end of each stage the game would be less frustrating, but that was your design choice. Also, the cards come random, so sometimes you can't move, and other times you can't attack.
But that makes you think a lot more at your strategy, like trying to kill the blue one first to not let him change the order of the actions.
Some problems I had: In my ultrawide monitor the UI goes off the screen, so I had to play in my laptop's screen. Also, if I click into a card, I cannot cancel my action (also, a design choice, because when I select an action the enemies also decide their actions).
Nonetheless, this game have a lot of potential! I really liked it, and would be happy to see that game evolve and turn into a full game!
Congratulations!
