I had a great time playing this game!
The difficulty is very progressive and there are plenty of elements to avoid, without it being impossible.
I found the fishing mechanics perhaps a little tedious. I think I would have preferred to click and release the left mouse button to move the green bar up and down, rather than having to turn with my cursor. Of course, it would have been less in keeping with the theme, that's for sure.
But the game was interesting and fun enough that it wasn't a problem :)
Well done!
