I don't know where to send feedback, so I will post it here.
I'd like to thank you for the GREAT work you've already done making a game which I can now enjoy. Mostly I'm testing different decks and card combos, that's why I'm looking for an option in the future to make custom opponent deck.
And here is a small bug report:
When player wins because opponent can't draw a card, game doesn't stop and AI continues their turn. So player needs to quickly click "Next" button or will be forced to play another turn.
If a status icon expires, the tooltip doesn't disappear and follows the cursor until it points to another icon.
There is a misprint in battle log for reducing damage moves: damage done will be reduced nect turn.
Also there are some cards which work not as expected:
Pidgeot's Hurricane sends opponent cards to discard pile instead of hand.
GB Jigglypuff's Expand doesn't deal damage.
GB Pidgeot's Gale deals 30 damage instead of 20.
Vending Clefairy's Sing costs 3 energy instead of 2.
Vending Fearow's Quick Peck deals 50 damage without coin toss.
