Yes, levels between 1 and 2 are missing for time reasons. Level 1 was teaching the basic concept. Level 2 for teaching the real basic concepts and Level 3 to have fun.
With more opponent model variety (and time) we could have done one level where you have to block a choke point with your dice (because the opponent can't fall over and is to strong in melee for your archer) and one where the opponent has infinite life and must be knocked over. This would have teached the concepts necessary for lvl2.
Maybe also something where you are taugth that you have to place the camera correct to roll the dice precisly.
Personally i like things that are difficult though.
