The concept of this game is quite interesting and I like how accurate the shadows all look. Some more gameplay elements would be nice to make the levels feel more different, like mirrors, multiple boats to save, or patrol boats that also have lights and move which you have to protect your boats from.

Some polish is needed but the main idea is quite good, although I didn't really find anything unexpected. Also, there needs to be a next level button because I kept having to go to the main menu after every level.

It was hard to notice when you were taking damage as there is no sound or visual indicator other than the small bar on the left, I often lost without even realising how. Maybe add some sound effect or make the borders of the screen change colour.

It works well, very little game, I didnt find too unexpected the game and I found the secret =D

Nice one

I like the mechanics of avoiding the boat from being detected. I think you need to add a “Next Level” button since I kept forgetting what level I was at. :-D

In local news, suspicious rock spotted near lighthouse. The idea is pretty funny by itself, which makes up for the gameplay which is ok but not great.

This is overall a simple and fun little game. Well done.

I love the "Congratulations ... what are you looking at" screen :)

Interesting concept and unexpected indeed! 

Could do some more balancing there but overall nicely done
