A downloadable game for Windows

GMTK Jam 2019 game. 

This is my first game ever so please keep that in mind!! <3

Card game inspired by Slay the Spire, but you only have one hand to play.

Since you have a limited number of cards, the puzzle is knowing when to play them.

Armour decreases the damage you take by 1 per point. Strength increases the damage you give by 1 per point. You cannot deal damage with strength unless you have attack.

Fun little game I beat in less than 10 minutes. However, I ran into a weird bug where it froze after I lost and the screen wouldn't respond. I used task manager to close it, but you can't play again until you open the game and hit the exit button. Only froze the one time though.

Personally, I thought this was going to be a random pull from a deck of cards, not a static hand for each faction. That would have so much more replay value then.

A fun game!
