Yes. Once would be unplayable as it would depend too much on luck. And to be honest it took me several minute sto understand it. Even past that point where I already gave up and opened the next game. But then I just wanted to figure it out :D
And the idea with the breeding limit actually is from the game TemTem (not sure if you know it) where I spend a lot of time breeding the strongest combination. And I remembered that after clicking the breed -> trash combination so much in a row and my brain just expected it to say that I can't breed that fish anymore :D
