Hello! Just replied to this same question on another comment. Long story short: at first, the game ended as soon as the coffin hit a wall, but, 30 minutes before the deadline, we decided it should actually bounce a few times before it ended so the game wasn’t too short, but we didn’t have time to add some sort of health bar that made it clear! If the coffin hits a wall 15 times, game over. Sorry about that!
Also I laughed at the party thing. It’s not super playable right now. I didn’t handle the lag correctly so sometimes the coffin doesn't get hit. Also, asteroids become invisible on the clients — oops!
