This is so close to being an excellent game, the only thing I think it needs is a better UI layout.
The roll and attack should either be on the left or lift the dice and put the roll and attack in the centre.
Rather than the word attack I think you should use something else, because your attack is also a defend, perhaps "Fight".
Love the art and the character movement, great game design, just needs the UI changes imo.
Could be a huge mobile game.
There is something Slay the Spire about it.
