Really solid entry! Very fun to play
Card designs were all nice, and I didn't feel like there were any that were too out-of-balance.
Would be nice as a simple phone game.
My main gripes were polish related, being able to just press on a card to activate it instead of dragging it out would be nice, and also something to show how close a card is to going away.
also please idiot proof it and make it clear that upgrades are not permanent so dummies like me don't immediately spend all their turrets at once.
