Very well polished. Your game is entirely UI, but the style and animations elevate it
The rock, paper, scissors mechanics were easy to grasp, and the inclusion of a tutorial was a good idea for a game like this. Although I don't recall the tutorial explaining how to use your hero powers, that took me a while to figure out. It also tells you to press the "Use" button although the button is labelled "Destroy" which could be confusing
Being able to go directly to the shop between runs without going to the main menu could improve flow
It was a bit of a bummer that in a 1v1 trade, you didn't get any benefit from winning the rock, paper, scissors matchup. I'd suggest in that case the player should keep their card if they only destroy a single card that they would win against
The game was engaging enough - I managed to unlock everything. The Warder with an Elite Knight can make some pretty good combos. Good job!
