The game has a myriad of minor issues which include the number of fishes being fiddly, creating too many fishes can consume table space, the decision space is shallow, and tracking interactions can be taxing to remember who is what.
But all of these end up be strengths, the counting of bits for setup kinda doesn't matter, you can make a mess of your economy but still have fun, you are never too stuck in the numbers, and though tracking and be taxing, you are always curious on other player's turn to see if theirs actions will reward you with some food.
And in the end you make some silly fish, and maybe throw on some deep traits, and laugh. It's a great game for those learning about engines and economics, or those not looking for anything heavy nor light.
