As for me, the game has a great balance. It is clear that the author has put a lot of effort into creating the game. On the other hand, the mechanics of extracting cards are very tedious. You don't just need to click, but move the mouse back and forth across the screen several times. Right now I have about 5k extracts. And according to my estimates, I have opened 25-35% of the content. This means that I will need to swipe the mouse one or two hundred thousand more times to complete the game. This thought makes me lose the desire to play this game. Even though I really like it.
