Very neat concept and presentation. Card games like this can be dangerously addicting. Also I'll try to be the man Chad Dog believed I could be.
Once I realized that nothing would stop me from doing [SPOILER] (confirmed by the info you shared) I tried to do it but I don't understand if I'm doing it wrong (like there's a specific moment I have to do it) or if it is working as intended (still, the idea is pretty fun).
Great work.
