I'll put my feedback into a list:
- 1: Instructions would be nice. Took me awhile to realize how to even play the game, and even after beating every opponent I still don't know how to get rid of dice (if it is even possible) or how I added a die after I already had a full deck.
- 2: For the User Interface, it would be nice if it would show how much HP the opponent has. Since it is possible to have more dice than the menu indicates, being able to check the bag would be good. A map to keep track of your progress and possibly fast travel, and a compendium of the met waifus would be nice.
- 3: Faces aside, the only dice effect I understand is the zombie's. Would recommend making it more clear. The summary says "Each Waifu has distinct passives that completely alter the game board rules and manipulate your dice rolls." but I couldn't notice which is probably because I couldn't understand. The zombie dice was also overpowered, would recommend reducing the face values to balance it out, possibly as low as 0/0/1/1/2/2.
- 4: From what I can tell, the game is essentially dice-blackjack. But you have so many dice that means higher values are essentially pointless if not outright detrimental. I would recommend making it that when one player Stands the other only has one more turn to roll (barring a dice ability) to make rolling high then Standing early a viable strategy.
- 5: More explicit art, possibly progression-based. Since it has "Adult" as a tag all's fair. This could be the case already and connected to the "Meaningful Choices", but if so I must refer back to Point 1. If they're planned but you're open to ideas let me know, I notice that the Imp claimed I was "back again" despite encountering her for the first time, and she also seems to have to most provocative defeat art.
- 6: Smarter A.I. I notice some will Stand early, but that doesn't make sense with the game as it exists; they should at least play until they reach a point where continuing is a risk, and they have to keep playing to try to win if the player is ahead of them. This could be done with a difficulty mode, especially one where the enemies have mixed decks (albeit still primarily within their theme). As an example and in conjunction with my zombie rework, the Imp could roll two of her unique dice, then roll zombie dice to edge to victory.
- 7: An idea for a gamechanging dice: "Lower Roll Wins". When played, the higher value loses (not counting if the LRW-roller busts). To prevent it from being used willy-nilly, it should have a high value itself (just over half would be 9/9/9/9/9/9) and be a counter to the high-rolling dice, especially if point four is implemented.
