I had trouble with placing the cards consistently until I realized that it wanted me to drag it to the top part of the point, not the middle. I'll admit, the thought of card combat intimidated me until I realized that trick-taking was a concept from normal card games, not modern video game ones.
I was able to pick up how to play without any issue, although I swear there was one time that I thought I should have won but no damage was dealt. The combat mechanics were interesting, although I would've liked another modifier to spice it up by the end.
The final fight got down to the wire, but I managed to pull out a win. Good work!
