This is an enjoyable little exploration game, and I appreciate the inclusion of a mouse sensitivity slider for player comfort. While the gameplay loop is straightforward and easy to grasp, the execution feels a bit rough around the edges and could benefit from some refinement. Considering it's a one-week solo project, it's certainly a commendable effort. For future development, focusing on enhancing the overall user experience could be beneficial. This might include options for adjustable difficulty or reducing the number of sharks near the surface. Despite these minor issues, I commend your efficient utilization of available tools, such as the sprint button and the detailed menu and tutorial. Hope this feedback is beneficial for you and your future in game development :)
