Haha I saw your review on Dreamsteria and had to come play your game :)
At first I didn’t see the upcoming enemy attacks at the top and I was trying to figure out the strategy but eventually it clicked. The sound bug is a shame especially if you made all the sounds :( The art is great and I like the exchange mechanic a lot
For some constructive criticism, I also experienced the web resolution issue. I think the shield and damage-through-shield icons are a bit too similar to be readable. This is super minor, but I don’t think the first boss should reduce cards in your hand - I feel like part of why I thought it was so on-rails was that I didn’t have enough options on the first boss and it would be cool to demo all the different card varieties.
