I like the theme! I have some suggestions and comments.
Regarding the game, is there a luck mitigation mechanism to reduce the luck of the dice roll? Then player can strategies and land on the right square to level up.
The power of player cannot exceed 250. I supposed it is a catch-up mechanism. Defeat reduces the power. Quite interesting choice for player.
The game is 2 to 4 hrs. May I ask what is the typical duration per player?
All the best!
