I love this hand-drawn art style of the game, it looks so adorable! Not too sure about the gameplay, currently it feels too luck-based and a bit bare boned. It's basically boiled down to what the dice numbers are and what card you've got. I think the game would be a lot better if there were more choices and options to play around with, just to increase the mechanical depth of the game. On top of my head, one suggestion would be multiple stats like attack, defence, avoidance etc, and multiple cards to choose from. Systems like these would surely encourage more tactical decisions to be made, and thus more fun!
Anyway, I see the effort in making this game, and it's already a feat to complete the game in the first place! Keep uip the good work and continue making games!
