I like the concept, but you can get screwed over by the RNG sometimes. I had a run where I drew 3 shields in a row and nothing to stop the enemies. I'm not sure if you are actually simulating a deck or just giving the player a random card, but you may want to try a simulated deck with a heavy weight on warriors.
Overall I like the game, and I could see it being really fun with a deck-building progression system added in!
@sirtyler Thank you for your comment. This project is totally lost control... hahah, I wasn't do Numerical management right and design too much cards but not implement it enough.... Hope I can do it better next time.
I like the idea - found it a bit too hard to get going, maybe you could fix the first few cards to give players a chance to win first time. I can see this being really fun with a good card drawing algorithm behind it. Well done on getting something out!
