This is so cool already!
First win, on my fourth attempt! On the third, the skull sniped my tower right as it was around 10 hp and last enemy standing, on the final night lol. I really couldn't come up with any harsh feedback! All I ever noticed was that knockback stops working fast, because enemies collide on each other, and there are oftentimes more bomb relics than bomb cards to choose.
Looking forward to what's next!
