This is an awesome game!
One minor UI nit: it should be sufficient to drag a die onto any part of a card, rather than only onto the center.
Hey thanks for trying our game! :D
Thank you also for the feedback :D. Currently, we don't have any plan to update the game, but if we do it, we will keep this in mind :D.
For your information, this game is heavily influenced by Dicey Dungeon. If you like this type of game, I really recommend that you check that game out :D. Cheers!
