This minigame is a good example of what the jam was looking for, I believe.
I bet you could get better scores when playing with dedicated friends, since the gameplay is completely chance- based; this will really test your determination to reach the highscore.
I hope that gameplay will be kept just as simple as the current one in future releases, because it really makes it a special competitive experience.
Post- Jam development should focus on:
polishing player experience (e.g. change the background for all players when one reaches certain score milestones, represent player scores in the lobby space);
implementing a crude betting system to keep players engaged.
