this is a very cute and polished game that has exactly the right amount of challenge for what it feels like it's going for. i had a really great time playing it!
my only note is that while the changing fish order each time you play creates better replayability, it also changes the difficulty a bit. my first time playing i had a fast smaller fish in the top row and it was very difficult not to pick it up by accident almost every time it was in the water. in my second time, all the fast fish were still in the upper 2/3rds but not right at the top, which felt much better to play. that being said, this is a pretty minor gripe that doesn't impact the quality or fun of the game.
