Very nice visuals! Even comes with a narrative comic strip.
Really liked the concept of this game. A creative mechanic for sure, would love to see it play out as intended. Multiple game modes (combat room) are a pleasant surprise for a gamejam! The starting tutorial, though brief, was helpful in explaining the game. The multiple game music tracks and effects also work well together.
I ran into some bugs. I think there wasn't a limit to catch the number of actions i could simultaneously input, resulting in the excess being deducted from my action points in the subsequent turn. Also, I ended up softlocking the game by running out of cards on a tile which has no possible moves (can't advance my turn, can't get the catacombs to progress).
Lastly, a small QOL improvement during combat would be for the player to face the direction of the mouseclick, and for the projectile to fly in the same direction. Having to turn to face the direction first seems to defeat the purpose of a 360 crosshair, and makes combat feel slightly clunky!
Solid effort overall!
