Yes I enjoyed it, even though I don't really play platformers/arcade games much. Penguins however were constantly getting stuck in little holes, making the game very easy sometimes, moreover if you went AFK for some time in the beginning of the level, almost all penguins would be stuck in these holes, since they're constantly wandering around. I also noticed that they're trying to move in the direction of the bear sometimes (although not all penguins, sometimes there're 1-2 penguins who don't join the crowd), so you can lure them in these holes or to the bottom. It means, that because the time isn't limited, you can potentially never lose a fish or punch a penguin, if you have patience. Timer will probably make this game worse, as currently this game is rather relaxed. May be slowly increasing sea level will work? Or may be your score will slowly decrease, to ensure that players can't abuse penguin AI too much. Or may be you can teach penguins to jump/climb up? :D
