The mechanics are definitely there. The way the dice control you attacks is handled well. It looks like it just needed more time to be polished.

Unfortunately as it is unfinished it is hard to grasp how good the game is.  However, it does bring some interesting ideas. With more time and development, I could picture this being a fun deckbuilding roguelike, like slay the spire, and the player thinking how to best influence rng to their advantage. giving rerolls is a very helpful option, but you could do with a clearer way for the player to distingush between the reroll phase, and the action phase.
