First off: Not a game dev.
Secondly, it's a neat concept, and I had fun with what I played of it. Once I got a handle on the controls, it was quite enjoyable. Only two issues, from what I played:
- If there's a way to exit the game, I didn't see it, so I had to use the Windows key, and close the program by right-clicking the taskbar icon.
- You can get caught even if you so much as touch the fishing line.
Keep up the good work; you've got a nice little concept here!
