Thank you for your comment.
The dice picking part was supposed to be part of the decision making in the game. The player will be given an amount of dice roll for one turn and supposed to choose between quantity (number of action) or quality (level of the action).
Debuffs works on enemy, so it is a plus for the player, but as commented the UI part and feedback is quite far from finished hence the intention of the action selected is not correctly communicated. The description given when selecting the crest was supposed to help explain the effect, but currently it really didn't help much.
Thank you for the compliment on the theming and art direction. The chess piece was the choice of my team member. Have to thank him for his sense.
We are planning on continuing the development for this game, so if some time in the future you happen to remember this game please feel free to give it another try.
