There is a good amount of mechanics that work very well together. Having to reel in and out was a good mechanic to implement.
The character reminded me of Luffy from One Piece haha.
I think having a mini tutorial to help the player catch their first fish would have made it easier to get the hang of things, but fortunately when the fish did hook on, everything was pretty intuitive from there. Also clamping the mouse movement a little when moving around and driving the boat would have helped as I did feel quite dizzy in some points (but that's mainly on me for not wearing my glasses hahaha)
Overall it was a very nice entry, very relaxing - could see this becoming a nice cosy adventure game in the future!
