Wow I really enjoyed this game! Can certainly feel the 'Slay the Spire' influence but I think this stands up by it's own accord as well. I enjoyed the many card combos in the game, and was having fun finding new cards and thinking of ways they could be added to my deck to make stronger and stronger combos. I thought the animations and effects in the game felt really great and once I realized what all the UI elements were, it was really easy to understand the game state at a glance. After I beat the boss I kept playing to clear the entire map out of enemies because I didn't want to stop playing yet. I also ended up playing through a second time with my teammate watching to show them the game.
The only negative I will say is that I wish the player and enemy sprites were bigger during the combat section of the game.
Overall, very impressed and I had a great time playing it. Nice job!
