The idea was cool, and I really liked the game overall. The art style is really well done, but I had a few issues with it. There is no sound in the game, and there isn’t much feedback when I attack or perform actions, so the game felt a bit slow.
The game was most fun when both the AI and I had cards, and I had to switch between trying to attack and hoping to collect something good, that was amazing. However, I noticed that many times, if I found something and the AI didn’t, I could win very easily on the next move. I think starting with the same card, or something similar, could help make the game feel more balanced.
