Hi Yuuni, thanks for the serious comment.
1. Yes, we need to think about how to keep players in the mental flow by introducing new game experiences in the progression to avoid boring issues.
2. Speed up the leveling up session for quick reward is a good thought to enhance the positive loop.
3. Just as you said, we definitely will add more new interesting powers and mechanisms around the dice if we keep developing this. Giving players the choice to select which power to take is a good suggestion.
4. It seems the collision is a problem in the later game, we might disable that between players and enemies in the future.
Thank you again for playing our game and sharing your experience and thoughts!
Best
