Maybe I missed it but i struggled to understand or see fire shrimp and moon algae doing anything. I ended up wasting my money on them and my turtles all died. I also dont really see the mutations in the turtles. Maybe better explanations of whats going on and why could go a long way! The game is really charming tho and I love owning a little turtle habitat and seeing the different turtles. Despite my gripes this is an awesome game.
