DUDE. This one is a TON of fun. I didn't know you could shoot the OTHER PERSONS card until halfway in and that took it from a pretty good twist on blackjack to a great concept. Great use of luck manipulation!
In hindsight, scrolling past the edge of your cards to reach the enemy's cards might not be the most intuitive control scheme... But yeah, I deliberately made the enemy behaviour very predictable so you know how to most effectively screw up their hand.
