I did like this one and I think it could be pretty cool with a bit more polish. I ended up dying about three quarters of the way through and I'm unsure how, I believe I had 12 health and instantly died on next turn. I think a way to see your current deck on the pick cards screen would be helpful potentially. I also had to mute the audio because there was some clipping in the music outside of the boss fights. Making a functional game in this genre in a week is impressive though honestly, well done.
