I think the premise of this game and its minimalist visuals are absolutely great, but the execution was rather rough. Aside from the difficulty which others have already touched on, I managed to get stuck in rocks multiple times, making it necessary for me to reset often. When I tried to adjust the camera to get a good top down view, the camera snaps and disorients me (I've personally run into similar issues before: try to avoid allowing the camera to be perfectly vertical and cap its angle to something very close to vertical instead). Causing a ripple when I only mean to move the camera also resulted in me sending the boat the wrong way relatively often, though I eventually realized I could use RMB instead of LMB for that. There's definitely potential in the idea, though :)
