I see the game was ported with the legacy CheerpJ 2.3 runtime. Consider upgrading to the new CheerpJ 3.0. Improving boot times has been one of our main goals and upgrading is very easy: https://cheerpj.com/docs/migrating-from-cheerpj2
Fun game! I thought you programmed it wrong till I realized in your version of liars dice 1s are wild. Also never played the way of guessing the total number of dots, and we always have loser go first on the next round. Thanks for sharing!
