Ah yes I totally see where you are coming from. I played a lot of Dorfromantik lately (a tile based card game), which does not have a real goal either other than getting the highest score possible, so I thought I could get away with it as well :) I just wanted it to be very chill without putting too much pressure on the player, so I made the robin way less aggressive than originally intended.
next time I'll try to come up with a more engaging solution.
thank you for playing and for your helpful feedback!
