Oh I think you did a fantastic job with this one.
It's perfectly nice and simple, and I like the intro that adds just a bit of background.
The color scheme is used very well, and I love the use of silhouettes.
I found it slightly difficult to understand how the fishing timing worked, but I managed to get a combo of 5. Plus, i finished the collection!
... also I think the music doesn't loop forever, after playing a while it went quiet.
Besides that, it's a very good entry - Great work!
