Excellent, absoletely stunning use of the theme -- there's a tension between choosing collecting fish or trash because of the oxygen countdown. The pixelart is lovely and the gray-green tint and trash adds a fittingly sad feeling. Controls were a bit clunky. The experience of encountering a whale or a sunfish suddenly for the first time is fun. I've learned things too about scientific names, which is neat. I encountered a minor bug where I was typing a name and the inner monologue also appeared -- and then I couldn't hit enter on the typing window, so the battery ran out. I liked how the battery running out separately from oxygen is a way to help players look for something else to do, something beyond the instructions. Very well-executed! Not exactly comfy/summer-themed. However, centering the topic of ocean pollution and cleanup even when things feel hopeless is vitally important. Thank you!
