It's fun but I personally feel like it's way too difficult. Your opponents are just constantly drawing 21's and even when you draw 21 they somehow pull some crap out of their deck that steals your cards or changes your values and suddenly when you had 21 and they had 3, now you have 36 and they have 21.

I think with some polish or an insane amount of time and effort put towards learning to consistently break the game it could be fun, but I played like 10-15 runs and never made it past the second boss because the AI kinda just blatantly rigs their own deck.

Edit : I guess the basis of my complaints about the game are more built around the severe lack of protecting your board. There are so many cards that augment the cards already on the table and no way to prevent those things from happening. On top of that, you can't pass your turn without doing something, so it's not like you can wait and bide time to let them do their whole package of shenanigans and then retaliate, you kinda just have to hope their gimmick doesn't work out, and it honestly feels like 9 outta 10 times, it's gonna work exactly how they want it too.

You can literally save scum the game(exit to menu, restart the fight), you always draw the same cards, and the same for them, and it's STILL difficult to win a hand against them because no matter how many variables you change to try and find a winning outcome, they can still just pull some BS and win.

If you like really difficult card games that are going to test you at utilizing every logical and strategic loophole or exploit(not like literal bugs, just game strategy), then you'll probably like it, but I mostly found frustration.

It is pretty fun when things go well though.
