I feel like being able to set the win condition to 100 points for example would be more fun and would give players more chances for a comeback. I've played a few rounds now and basically the game usually ends with round 3, which feels like a waste for such a great combo-building concept.

Agreed

I've never finished a game in 3 turns.
And according to BGA, your average is 8 or 9 turns

During game development, we tested many different configurations, and the drawback of setting the end of the game to 100 hearts is that the emotional impact would drop well before the end.
