The game was sort of fun, but I felt like there was one major problem holding it back: it doesn't really know what game it wants to be. It feels like it's trying to be a battle royale, an idle game, and a deck builder all at the same time. You need to pick a genre and stay with it. You can't have quick reactionary trap placement, and then also have strategy deck gameplay.
If you want fast-paced battle-royale-style gameplay, I would invest more resources into making sure the GUI was more intuitive and responsive as well as tuning the decisions to be more obvious what you need to do, just difficult to manage everything at once.
If you wanted to go more down the idle game path, making the enemies have more health/more cards that do stuff over a long period of time as well as getting cards less frequently would be a good idea, so you have more time to plan your decisions while the battle ensues.
If you wanted more of a deck-builder strategy game, then add a pause button, since you can't read the cards if you're in the middle of the action, as well as put more resources into developing a more diverse deck that would lead to more strategic gameplay.
I have no idea what kind of game you were going for, but whatever it was, I think there's a glimmer of a good game in there somewhere, if you keep developing it, maybe you can bring it there.
