Nice to meet you, I am a Japanese user, so I apologize in advance that my English may be poor.
Now, I think this mod is very great for a test version.
I felt that the balance of the 4 characters was adjusted and any character can win.
Now, I have played this mod many times with my friends and have the following complaints.

・the lizard tails don't work.
There is a bug that even if you have a lizard tail, once you die, you are treated as a loser, and I would like to see this fixed.

・You can't predict your opponent's next move.
I think it is too difficult to know what the opponent will do next.
Of course, it is one of the fun of the game to predict from the previous actions, but if you don't know at least what your opponent's next move will be, you don't know anything, and it is boring.
So, I would like it to be possible to know what the opponent's next turn's cards will be.

・I can't immediately tell what kind of cards my opponent has in his hand.
Since it is necessary to look carefully at the illustration of the cards in the opponent's hand before understanding what kind of hand it is, I would like you to create a "prediction of enemy action" type of icon display, for example, an attack 6 for strike and a shield icon for defense, under the opponent's card.

・Certain routes are too weak.
Even if you go through the events, there are many useless events, and the route that goes through the store twice is too strong.
Also, the treasure chest route is not reliable, so I am disappointed when a weak relic like the smiley mask appears.
I would like to see only beneficial events/relics appear.

・Certain cards are too weak/strong.
Some cards are too weak, such as the Silent card that sends discarded abnormality cards to the opponent.
It is too difficult to discard the card in its current state, and even if it is sent, it does not interfere much, so I would like the card to be more usable as a standalone card.
I think the "send wounding when you damage an opponent" skill is a very good balance.
Another card that I think is too strong is the Time Eater card.
You have to take at least one of them to be at a disadvantage.
I think it would be better to set the cost to 3 and then upgrade it to 2.

・It is hard to narrow down card picks.
Due to the specification of "Relic Deliverer," it is very difficult not to take cards you don't need.
Even if you don't need the card, you have to buy it to find the card you need, which is very stressful.
So, I would like to see a specification that makes it easier to get the card I need. (Such as making it possible to go through the store up to 3 times).
Also, there are too many strikes/defenses and it is difficult to make a combo between cards.
So I would like to see those cards reduced, such as removing 3 strike/defense cards each.

∙ Some potions are too strong.
Some potions, such as fanatic and power potions, seem too strong.
I think these need to be balanced and made weaker.

・Neo bonus, the option to lose the initial Relic and get the Boss Relic is too strong.
Due to the nature of this mod, the choice to get a boss relic is too strong.
The initial Relic does not do much in combat and is completely useless in regards to the Ironclad Relic.
In addition, there are many strong relics that have almost no disadvantages, such as coffee drippers and fusion hammers, and many powerful relics, such as astrolabe and pyramid, which make the boss relic option practically the strongest.
Therefore, I would like you to make the other options stronger and change the current situation where the boss relics are the strongest.

・I would like you to make it possible to fight in a series of battles.
This may be technically difficult, but it is hard to enter the server address each time, so I would like it to be possible to fight again immediately without having to do so.
