The ideas was very interesting, and the getting waves to form was satisfying, but maybe I just am not a true gamer I was struggling with the little guy in the canoe. I had to reset because my tentacles got so long they would spaz around that is how after I restarted (they guy flew off the screen) my big tentacles hit the guy and his cursed canoe! but then the second level felt much easier, the third took a bit but felt doable. 

I would make clock wise circles usually to the left of the target to make waves and just move in those circles and try and time them to make them bigger not sure if I was doing it wrong. 

 If you are using unity if you go to the canvas you can lock the ui to be anchored to a specific point

nifty Idea , I thought the water physics was interesting.

I love the physics and enjoyed the gameplay quite a bit :)

I would just limit movement so you can't go off screen.

ElScorscho my head keeps falling off

but I enjoyed drowning people

I had fun messing with the waves, that was a good idea! I particularly liked the shape of the kraken before pressing any keys, it might have been a nice touch to find a way to get the tentacles to return to that position when idle.  I had the tentacles shoot off across the screen a few times and one time the small boat shot across the screen and was lost. Those are pretty small quibbles though. The premise and fun are clear and present.

Water physics are wonky but in a fun way. Added sfx would make this game better. I beat it all using the same strategy. 

This game certainly matches the vibe you are going for in invoking a "totally Accurate" simulator!

I really like that the BGM shifts as you close in on the target.

My greatest suggestion for polish would be to have an option to return to a main menu/beginning of the game when you clear the last level. Right now it feels like it freezes!

Nice approach to sinking the ships! I love it.
