It’s an interesting game mechanic that combines dice with Rock Paper Scissors, but wanted to have a few more features for players to choose from.

Nice pixel art! 

Although, at the moment there's not much a player can do. If the game can be expanded on a bit, like if the dice has rock, paper, and scissor faces (i.e. 2 rock, 2 paper, 2 scissor), I think it would lead to very interesting mechanics!

For example, when a player loses the roll, they may choose to "reroll" that dice again with the cost of replacing the current face with a "curse" face, which result in instant-death or damage when rolled.

Maybe a player has a limited number of dices. When the dices run out, they dies...

Maybe enemies also have rock/paper/scissor faces on their dices, and each enemy may has a different set of the faces corresponding to their concepts. (e.g. "Grim Reaper" would have all faces be scissors!)

อยากให้เพิ่มบทบาทของผู้เล่นอีกหน่อยครับผม ผู้เล่นทำได้สุ่มว่าจะแพ้หรือชนะอย่างเดียวเลย ไม่ค่อยมีบทบาทเลยครับผม
