Surprisingly fun card game that really fits the theme well.
It starts off slow and I was afraid it would be a generic card game there. But the new cards really made the deck work better and better. There sure are some different builds possible with this.
There is no maximum hand size, but the game also doesn't allow you to scroll to cards off screen. I was able to double the Draw 6 cards prep and sadly there were a lot of cards off screen that I could not reach.
Also for high scoring rounds, consider showing the fish scaling animation as scaling multiple fish at once. My best round was 9 fish in one round and I think you can get much higher than that even, but the animation, although lovely, is the same each time so waiting for 9 fish to be scaled is just a lot of wasted time then.
Great job on this one !
