I really like it! You start every level being very careful about your movements and you end it being a menace, mindlessly eating what were giant obstacles previously; such a good feeling. The emergence of submarines was an unexpected twist. As for feedback, the cooldown period after eating might be overly lengthy, leading to accidental bumps. Additionally, the size disparity isn't always a clear indicator of what is consumable, leading to very avoidable deaths. I hope we get to see how hungry this tetra can truly get in a update/sequel.
