I love this game, but I think you can change the move buttons to ←and→, it's wired to only use one hand to play the game. And I can not find anything about roll of the dice...
Thank you very much for your advice! I have added some introduction to the itch page, I forget to explain about pieces. It could be hard for me to make an AI in such a short time QAQ. Anyway thanks for your playing!
