Really like the game idea, the concept of needing to make quick balancing decisions "I get this, but my enemy get's that".
I will say the only time I was able to win was by spam clicking accept through all the cards immediately. Maybe you stack the deck in a way that if someone does that it leads to defeat? (like a casino, where the house has an edge, forcing the player to pick strategically instead of chaotically)
Cool game, would love to follow its progress if you continue working on it outside of the game jam!
